Sorry Something Went Wrong Facebook Error
The key flaw that triggered this outage to be so extreme was an unfortunate handling of a mistake condition. An automated system for validating arrangement worths ended up causing a lot more damage than it taken care of.
The intent of the computerized system is to look for arrangement worths that are invalid in the cache and change them with updated worths from the consistent store. This works well for a short-term problem with the cache, but it does not function when the persistent shop is invalid.
Today we made a modification to the consistent duplicate of a setup worth that was taken invalid. This implied that each and every single customer saw the invalid worth as well as attempted to repair it. Since the solution entails making a question to a cluster of databases, that cluster was swiftly overwhelmed by thousands of hundreds of inquiries a 2nd.
To make matters worse, every time a customer obtained an error attempting to inquire one of the databases it interpreted it as an invalid worth, and also erased the matching cache key. This indicated that also after the original trouble had actually been dealt with, the stream of questions proceeded. As long as the databases fell short to service several of the requests, they were causing a lot more demands to themselves. We had actually gotten in a comments loop that didn't enable the databases to recoup.
The way to stop the comments cycle was rather agonizing - we had to quit all traffic to this data source collection, which implied switching off the website. When the data sources had recuperated and the source had actually been dealt with, we slowly enabled even more people back onto the website.
This obtained the website back up and running today, and for now we have actually turned off the system that tries to fix arrangement values. We're discovering new designs for this configuration system adhering to style patterns of various other systems at Facebook that deal more beautifully with comments loopholes and transient spikes.
We ask forgiveness again for the website failure, and we want you to understand that we take the performance and also reliability of Facebook really seriously.
