Sorry Something Went Wrong Facebook
The vital imperfection that caused this failure to be so extreme was an unfavorable handling of an error condition. A computerized system for verifying setup worths ended up triggering far more damages than it dealt with.
The intent of the automatic system is to check for arrangement values that are void in the cache and also change them with updated worths from the consistent store. This functions well for a short-term issue with the cache, but it does not function when the relentless shop is invalid.
Today we made a modification to the consistent copy of a configuration value that was taken invalid. This indicated that every customer saw the void value and also attempted to fix it. Due to the fact that the solution entails making a query to a collection of databases, that collection was quickly bewildered by hundreds of countless inquiries a 2nd.
To make issues worse, whenever a customer obtained an error trying to quiz one of the data sources it analyzed it as a void value, and also deleted the matching cache secret. This implied that even after the original problem had actually been repaired, the stream of queries proceeded. As long as the databases fell short to service some of the demands, they were causing a lot more demands to themselves. We had gotten in a responses loop that really did not allow the data sources to recover.
The means to stop the responses cycle was quite excruciating - we had to quit all traffic to this data source collection, which meant turning off the website. As soon as the databases had actually recuperated as well as the root cause had been taken care of, we gradually permitted even more individuals back onto the site.
This got the site back up as well as running today, and also for now we have actually switched off the system that tries to remedy arrangement values. We're exploring new layouts for this configuration system complying with style patterns of various other systems at Facebook that deal more beautifully with comments loopholes and transient spikes.
We say sorry again for the site interruption, as well as we want you to know that we take the performance as well as reliability of Facebook very seriously.
