Known Error Workarounds: What the Zune New Year’s Eve Freeze Teaches Support Teams

A known error workaround is the most useful thing a support team can publish when there’s no fix yet, and it only works if it’s honest, specific and in every agent’s hands within the first hour. The Zune freeze on the last day of 2008 is a near-perfect example, because for most owners the official answer was a workaround that amounted to “wait, then recharge.”

I’m writing this a week after the event, while the forum threads are still warm. What happened to Microsoft’s 30GB Zune players isn’t really a story about a music player. It’s a story about what your desk says when the honest answer is that nothing can be done until tomorrow, and about how much that sentence costs you if it arrives late.

What actually happened to the Zune?

On 31 December 2008, 30GB Zune players froze on startup. According to NBC News’ report the following day, a Microsoft spokesman, Brian Eskridge, said a bug in the model’s internal clock driver mishandled the extra day in a leap year. Only the 30GB model was affected. The clock sorted itself out once 2009 began, and Microsoft’s advice was to let the device charge fully and then turn it on again.

The Register covered it on the day as owners discovered the problem, and Technologizer followed the story through to its resolution. The early message from Microsoft was vague: owners might see “issues,” please be patient. The explanation and the workaround came hours later.

So there was a gap. For part of New Year’s Eve, a lot of people knew their device was dead and nobody could tell them why. That’s the gap every support desk lives in during an incident, and it’s where a known error record earns its keep.

Notice what the failure looked like from the outside. The device didn’t throw an error message. It sat on a loading screen. To an owner, that looks exactly like a broken unit, a bad download or something they did wrong. None of those guesses was right, and every one of them would have sent them down a different, useless path. The cause was a date. You can’t troubleshoot your way out of a date.

What is a known error, and why does it matter here?

In ITIL language, a known error is a problem whose cause has been identified, with or without a permanent fix. The record holds the symptom, the cause, and the workaround. I covered how incidents and problems differ in what a helpdesk actually is; the known error sits in the middle. It’s the moment you stop investigating and start telling people what to do.

The Zune case had all three parts by the end of the day. The symptom was a 30GB player hanging at the loading screen or resetting on 31 December. The cause was the clock driver mishandling the last day of a leap year. The workaround was to let the battery run down or wait until the new year, then recharge fully and power on.

Three sentences. An agent on a phone can work from three sentences. What they can’t work from is “we’re aware of reports and investigating,” because that line gives them nothing to say on the second call, let alone the four-hundredth.

The framework treats this as a hand-off between two practices. Axelos’ problem management guidance puts known errors and workarounds inside problem management, and the people who use them inside incident management and the service desk. That split is right on paper. In practice it’s where workarounds go to die: the problem team writes a note for other engineers, files it, and the desk never sees it. Don’t let the record live only where the people who wrote it can find it.

Why is “wait” such a hard answer to give?

Because it sounds like you’re doing nothing. A customer who’s been told to wait hears “we don’t care.” An agent who has to say it a hundred times hears it too, and starts to soften it, hedge it, or invent something more active-sounding to say instead.

It’s tempting to think the customer wants a fix. Most of the time they want certainty. An answer like “your device will start working again once the date rolls over, and here’s how to restart it” is better than any amount of troubleshooting, because it ends the worry. The fix comes later. The certainty can come now.

That’s why the wording of a workaround matters as much as the workaround itself. Write it so it answers three questions in order: is it my fault, is my stuff safe, and when will it work again? If your workaround text doesn’t answer the second question, expect every call to ask it.

I used to think the hard part of “wait” was the customer’s reaction. It isn’t. The hard part is the agent’s. Good agents want to solve things, and a script that tells them to do nothing feels like a failure on their side of the call. Tell them plainly that the workaround is the fix for today, and that saying it clearly and kindly is the job. Then back them when a customer pushes. An agent who knows the lead will stand behind “wait” says it with a lot more confidence than one who suspects they’re on their own.

What should a known error record contain?

More than the technical note. The engineers’ version is usually accurate and unusable. The support version needs six fields, and here’s how each would have read for the Zune.

Field	What to write	Zune example
Symptom	In the customer’s words, not the engineer’s	“It’s stuck on the loading screen,” not “boot sequence hangs”
Who is and isn’t affected	The exact models, versions or accounts	30GB model only; every other Zune model is fine
Workaround	Numbered steps, ending with what success looks like	Let the battery drain or wait until after midnight, charge fully, power on, check the menu loads
What they won’t lose	Data, purchases, settings, whatever applies	Music and settings are still on the device
Next update	A time, even if nothing is expected to change	“We’ll update this at 9am on 1 January”
What not to do	Anything that would make it worse, stated first	Don’t open the case, reset to factory or reinstall firmware

The “who isn’t affected” line is the one most teams forget. During a widely reported failure, plenty of people with unrelated problems will assume they’ve got the famous one. A fast “this only affects the 30GB model” saves them, and you, a long call.

The “what not to do” line is the one I’d move to the top. When a device looks dead, owners reach for the most drastic thing they know: a reset, a reinstall, a screwdriver. Each of those turns a problem that would have fixed itself at midnight into a real repair. One sentence telling them to leave it alone is worth more than the rest of the record put together.

Keep the whole thing short enough to read aloud in under a minute. If it runs longer, the agent will paraphrase it, and paraphrase is where the wrong advice gets in.

How fast should it reach the front line?

Faster than you think is safe. If you’ve set up escalation triggers for the first twenty minutes of an incident, publishing a draft known error should be one of them. A draft that says “cause not yet confirmed, current advice is X” is better than silence, as long as it’s labelled as a draft and you update it the moment you know more.

The Zune timeline shows why. The first public message said very little. The useful one, with the cause and the workaround, came hours later. Every hour in between, the forums filled the gap with guesses. Some of those guesses were harmless. Some, like opening the case or flashing firmware, weren’t. Your customers will find advice somewhere. The only question is whether it’s yours.

There’s a reason teams hold back, and it’s a fair one: nobody wants to publish advice that turns out to be wrong. But a draft with a clear label is a different thing from a guess dressed up as fact. “We think this is linked to the date, we’re confirming, in the meantime please don’t reset the device” can’t hurt anyone. It buys you the hour you need, and it stops the most damaging behaviour while you get the real answer.

Speed isn’t only about the customer-facing words, either. The first version goes to the desk, the second goes on the website, the third goes into the auto-attendant message at the top of the phone queue. A recorded line that says “if your 30GB player is stuck on the loading screen, it will recover after midnight” answers the call before it reaches an agent. That’s the cheapest call you’ll take all night.

Who owns the wording?

One person, by name, for the length of the incident. Not engineering, not marketing, not a committee. Engineering supplies the facts, marketing may want to see the public version, but someone in support has to own the sentence the agents read out, because they’re the ones who’ll hear what’s wrong with it first.

A good owner does three things. They publish early, they version the record so agents know which wording is current, and they collect the questions callers keep asking that the record doesn’t answer. Those questions go straight into the next version. After a dozen calls you’ll know exactly what the record is missing. After fifty you’ll have rewritten it twice, and that’s fine.

Versioning sounds like bureaucracy until you’ve seen two agents give two different answers ten minutes apart. Put the version and the time at the top of the record, every time: “v1, 18:40, cause unconfirmed,” then “v2, 20:15, cause confirmed, workaround added,” then “v3, 22:30, added: music is safe.” An agent who picks up a call can see at a glance whether they’re reading the latest one. A team lead walking the floor can check the same thing in a second.

The owner also decides when to stop changing it. Late in an incident, every small improvement to the wording costs a round of re-reading across the whole desk. Once the record answers the top questions, freeze it, and save the polish for the review.

Does a workaround change what you owe the customer?

It can. In my post on why an SLA credit isn’t a remedy, the point was that customers judge you on how they were kept informed, not on the size of the credit. A workaround is the same idea in a different form. It’s not compensation, but it’s evidence that you understood the problem well enough to help.

For a consumer device that started working again by itself, nobody was owed much. For a business service, the calculation is different. If your workaround costs the customer time, effort or money, record that too. Somebody will ask about it later, and you want the answer to be a policy rather than an improvisation.

Here’s the test I use. If the workaround is “wait,” the customer’s cost is inconvenience and you owe them clarity. If the workaround is “do this manual step every morning until we ship a patch,” their cost is real labour, and you owe them a date for the patch and a conversation about it. The moment a workaround moves work from your side to theirs, it stops being a courtesy and starts being a debt.

How do you measure whether the workaround worked?

Most teams close the record when the incident ends. Keep it. The Zune bug was tied to a date, and dates come round again. A known error that reappears in four years, or that a different product with the same component could trigger, is far easier to handle if the record still exists and someone has written “check this before the next leap year” at the bottom.

Then review it once, honestly, with three numbers: how long it took to go from the first call to a published workaround, how many calls arrived before it existed, and how many agents gave advice that wasn’t in it. You can only count the calls if they were tagged to the incident as they came in, which is why a ticket category set up so it survives reporting matters before the bad night, not after.

Here’s the sheet I’d build. The figures below are a made-up example, not Zune data. Make a workbook called “Incident review” with a tab called “KE review.” Row 1 holds the headings. Column A is the hour since the first call (1 to 6, in rows 2 to 7). Column B is the number of calls tagged to the issue in that hour. Column C is the average handle time for those calls, in minutes. Column D is agent minutes, and the formula in D2 is =B2*C2, which multiplies the calls by the minutes each one took; copy it down to D7. Column E says whether the workaround was live during that hour, “N” or “Y.”

Row	A: Hour	B: Calls	C: Avg handle (min)	D: Agent minutes =B*C	E: Workaround live?
2	1	120	11	1,320	N
3	2	180	11	1,980	N
4	3	210	11	2,310	N
5	4	190	4	760	Y
6	5	140	4	560	Y
7	6	90	4	360	Y

Row 2 shows how each line works: 120 calls x 11 minutes = 1,320 agent minutes. Calls before the workaround go in G2 as =SUMIF(E2:E7,"N",B2:B7). SUMIF looks down column E, and every time it finds an “N” it adds the number from the same row of column B. Here that’s 120 + 180 + 210 = 510 calls. Put the same formula in G3 with D2:D7 as the last range to get the minutes: 1,320 + 1,980 + 2,310 = 5,610 minutes, and 5,610 / 60 = 93.5 agent hours. Swap “N” for “Y” and you get the after picture: 190 + 140 + 90 = 420 calls, and 760 + 560 + 360 = 1,680 minutes, which is 1,680 / 60 = 28 hours.

Now the first number, time to publish. Put the time of the first call in B10 (18:05) and the time the workaround went live in B11 (21:05). Spreadsheets store times as fractions of a day, so =(B11-B10)*24 in B12 turns the difference into hours: 21:05 minus 18:05 is 0.125 of a day, and 0.125 x 24 = 3 hours. Then the number that gets attention in a review. If the workaround had been live from hour 2, the 180 + 210 = 390 calls in hours 2 and 3 would each have taken 4 minutes instead of 11, saving 7 minutes a call. That’s 390 x 7 = 2,730 minutes, and 2,730 / 60 = 45.5 agent hours. Almost half the cost of the bad hours came from the wait for the record.

The third number comes from listening, not counting. Pull 40 recorded calls from the incident, and tick the ones where the agent said something that wasn’t in the record. If 6 of the 40 went off-script, that’s 6 / 40 = 0.15, or 15%. That’s not a discipline problem. It’s a list of the questions your record didn’t answer.

What would I do this week?

Find your three most recent incidents and look for the known error records. If there aren’t any, that’s the finding. If there are, read them as an agent would at 2am: can you answer “is it my fault, is my stuff safe, when will it work” from the record alone?

Then write a blank template with the six fields above and put it where your incident owner can reach it in under a minute. Add the version line at the top. Agree in advance who owns the wording on a bad night, so nobody has to decide it while the queue is climbing.

You won’t make a workaround arrive sooner by having a template. You’ll make it arrive in a form people can actually use. The fix belongs to engineering. The workaround belongs to you, and most customers will only ever meet the second one.
