Sorry Something Went Wrong Facebook Error
The essential flaw that created this outage to be so severe was a regrettable handling of a mistake problem. An automatic system for validating configuration values wound up causing a lot more damage than it taken care of.
The intent of the automated system is to check for arrangement worths that are void in the cache as well as change them with updated worths from the consistent shop. This works well for a transient problem with the cache, yet it does not work when the relentless shop is invalid.
Today we made an adjustment to the consistent copy of a configuration worth that was interpreted as void. This suggested that every single customer saw the void value and tried to repair it. Due to the fact that the solution entails making a question to a cluster of databases, that collection was swiftly overwhelmed by hundreds of thousands of questions a 2nd.
To make issues worse, each time a client got an error attempting to query among the databases it analyzed it as an invalid value, as well as removed the corresponding cache key. This indicated that even after the original issue had been repaired, the stream of queries proceeded. As long as the databases failed to service a few of the requests, they were creating a lot more requests to themselves. We had actually entered a feedback loop that really did not allow the data sources to recuperate.
The way to stop the feedback cycle was fairly agonizing - we had to stop all website traffic to this data source cluster, which indicated turning off the website. When the databases had actually recouped and the origin had actually been dealt with, we gradually allowed even more people back onto the site.
This got the site back up as well as running today, and in the meantime we've shut off the system that tries to fix configuration values. We're exploring new layouts for this configuration system adhering to design patterns of various other systems at Facebook that deal even more with dignity with responses loops and also short-term spikes.
We say sorry again for the website outage, and we want you to recognize that we take the efficiency and also reliability of Facebook really seriously.
