Sorry Something Went Wrong Facebook Error
The vital problem that created this outage to be so severe was an unfavorable handling of an error problem. An automated system for verifying configuration worths ended up creating a lot more damage than it repaired.
The intent of the computerized system is to check for configuration values that are invalid in the cache and change them with updated worths from the relentless shop. This works well for a transient issue with the cache, but it does not function when the consistent store is invalid.
Today we made a change to the persistent copy of a configuration value that was interpreted as void. This meant that every client saw the invalid worth and also attempted to fix it. Since the solution involves making a question to a cluster of data sources, that collection was quickly overwhelmed by numerous thousands of inquiries a 2nd.
To make issues worse, each time a client obtained an error attempting to query among the data sources it translated it as a void value, as well as deleted the corresponding cache key. This meant that also after the initial trouble had actually been dealt with, the stream of inquiries continued. As long as the data sources stopped working to service some of the demands, they were creating a lot more demands to themselves. We had actually gotten in a responses loophole that didn't permit the databases to recover.
The method to stop the comments cycle was rather excruciating - we needed to stop all traffic to this data source collection, which suggested shutting off the site. When the databases had recouped as well as the source had actually been fixed, we slowly permitted even more individuals back onto the website.
This got the website back up and also running today, and also for now we've shut off the system that attempts to remedy arrangement values. We're checking out new layouts for this setup system adhering to style patterns of various other systems at Facebook that deal more beautifully with comments loopholes and also short-term spikes.
We say sorry once more for the site interruption, and we want you to understand that we take the performance and also reliability of Facebook extremely seriously.
