Twitter: Sorry, but outages come with bigger improvement plan

By | June 15, 2010, 5:00pm PDT

Summary: Twitter says its outage problems caused by unexpected issues found while trying to boost capacity. Improvements are coming, but so are more outages.

There’s an old saying among traffic engineers about the traffic jams created by road construction projects that are intended to actually ease backups: “It’s gotta get worse before it can get better.”

These days, that seems to also be the rule of thumb at Twitter. (Techmeme)

In an effort to improve stability for times when it’s facing record traffic, such as during the World Cup, the company has launched efforts - both short-term and long-term - to grow capacity to avoid outages in the future. But it hit some snags along the way and discovered “unexpected deeper issues” that led to downtime.

From the post, it’s clear that the company anticipated demand around the time of the World Cup opening - the Internet itself set a new global record for news site traffic, surpassing the night of President Obama’s election victory in the U.S.  What they didn’t expect were these deeper issues.

So they’re working on it - and there are actually some details about what’s happening over on the engineering blog. And they say it’s going to get better.

But don’t forget what the traffic engineers say about improvement projects. With that said, Twitter issued this warning:

Over the next two weeks, we may perform relatively short planned maintenance on the site. During this time, the service will likely be taken down. We will not perform this work during World Cup games, and we will provide advance notification.

End of the day....

At the end of the day that is a hell of a problem to have as a company!! Only if they can not get it squared away over time and service basically stops, I would much rather have too much traffic then too little!! Any business would.

They will put resources including but not limited to more robust hardware, money, and of course human engineers and ultimately it will be solved.

I do not use Twitter or any of the Facebook's, myspace, etc, etc. I do not even have an account to any of these services but I appreciate how hard it is to scale to an ever growing demand of users and increased traffic.

You will hear some thoughtless morons that have never even seen a data center for a mid-size company handling a couple of hundred thousands of hits pushing maybe 80-90 Mbps who can not even comprehend the type of architecture it takes to handle that many connections and that much traffic.

Again...it is a good problem to have if managed correctly which it appears they are doing just that.
There are at least two flaws in your traffic analogy. First, "it" never really gets better; the traffic engineers just move operations someplace else even more fatal to traffic. Second, I've never seen a traffic project that actually improved anything. Add a lane? You get more vehicles -- as proved by every freeway "improvement" ever foisted on drivers here in SoCal. Time traffic lights? Hardly ever works properly, the average time sitting at a light typically lengthens, and it doesn't solve the problem of drivers trying to beat lights or jamming themselves into intersections after the light turns red. Patch potholes? The patches come up and make bigger holes. All of which is to say, Twitter is just squeezing the balloon -- they'll just create more problems someplace else. I garontee it.
