Is There Something Wrong With Facebook Right Now
The essential problem that triggered this interruption to be so extreme was an unfortunate handling of an error problem. An automated system for confirming setup values ended up creating far more damages than it repaired.
The intent of the computerized system is to look for configuration worths that are invalid in the cache and replace them with updated worths from the persistent store. This functions well for a short-term problem with the cache, but it doesn't work when the relentless shop is void.
Today we made an adjustment to the persistent copy of an arrangement worth that was taken invalid. This meant that every single client saw the invalid worth as well as tried to fix it. Because the fix includes making a question to a cluster of databases, that collection was quickly bewildered by hundreds of thousands of inquiries a 2nd.
To make issues worse, every single time a client got an error trying to quiz among the databases it interpreted it as a void value, as well as deleted the matching cache key. This meant that also after the initial trouble had been taken care of, the stream of questions continued. As long as the data sources failed to service several of the requests, they were creating even more requests to themselves. We had actually gone into a comments loophole that really did not allow the data sources to recover.
The way to stop the comments cycle was fairly unpleasant - we had to stop all website traffic to this data source collection, which suggested switching off the site. Once the databases had recuperated and also the origin had actually been repaired, we gradually permitted even more people back onto the site.
This obtained the site back up and also running today, and for now we've turned off the system that tries to correct configuration values. We're discovering new designs for this configuration system adhering to style patterns of other systems at Facebook that deal more beautifully with feedback loopholes and transient spikes.
We apologize again for the site interruption, and also we want you to recognize that we take the performance as well as reliability of Facebook extremely seriously.
