Something Went Wrong Facebook
The essential problem that caused this interruption to be so serious was a regrettable handling of a mistake problem. An automated system for validating setup values ended up causing a lot more damage than it taken care of.
The intent of the computerized system is to check for arrangement worths that are void in the cache and also replace them with updated worths from the consistent store. This works well for a short-term trouble with the cache, but it does not work when the relentless shop is void.
Today we made a change to the relentless copy of a configuration worth that was taken invalid. This indicated that every client saw the void worth as well as tried to repair it. Due to the fact that the fix involves making a query to a collection of data sources, that collection was rapidly overwhelmed by numerous countless queries a second.
To make matters worse, whenever a customer obtained an error trying to quiz among the databases it analyzed it as a void worth, and also deleted the corresponding cache key. This indicated that even after the initial problem had been repaired, the stream of inquiries continued. As long as the data sources fell short to service a few of the requests, they were causing a lot more demands to themselves. We had actually gotten in a feedback loophole that really did not allow the data sources to recuperate.
The way to stop the responses cycle was rather unpleasant - we had to quit all web traffic to this data source collection, which suggested turning off the site. When the data sources had recovered as well as the source had actually been taken care of, we gradually allowed even more individuals back onto the website.
This got the website back up and running today, and for now we've turned off the system that tries to deal with arrangement worths. We're exploring brand-new layouts for this setup system adhering to style patterns of various other systems at Facebook that deal even more gracefully with comments loops as well as transient spikes.
We apologize once again for the site interruption, and we want you to know that we take the performance and integrity of Facebook really seriously.
