Facebook Error Sorry Something Went Wrong
The essential imperfection that caused this outage to be so severe was an unfavorable handling of an error condition. A computerized system for confirming arrangement worths wound up creating much more damage than it taken care of.
The intent of the automatic system is to check for arrangement worths that are invalid in the cache and change them with updated worths from the persistent store. This works well for a short-term issue with the cache, however it doesn't work when the persistent store is void.
Today we made an adjustment to the consistent copy of a setup value that was taken void. This implied that every customer saw the invalid value and tried to fix it. Due to the fact that the solution entails making a query to a cluster of databases, that cluster was quickly overwhelmed by numerous countless inquiries a 2nd.
To make issues worse, every single time a customer got a mistake trying to quiz one of the data sources it interpreted it as an invalid value, and deleted the matching cache key. This implied that even after the original problem had been fixed, the stream of questions continued. As long as the databases failed to service some of the demands, they were causing even more requests to themselves. We had entered a responses loop that really did not allow the data sources to recoup.
The means to stop the comments cycle was rather excruciating - we had to stop all web traffic to this database collection, which meant switching off the website. As soon as the data sources had recouped and the origin had been repaired, we gradually permitted more individuals back onto the site.
This obtained the site back up as well as running today, and also for now we've shut off the system that attempts to deal with configuration worths. We're discovering brand-new designs for this arrangement system complying with style patterns of other systems at Facebook that deal even more beautifully with feedback loops as well as transient spikes.
We apologize once more for the website outage, and also we want you to know that we take the performance and also integrity of Facebook extremely seriously.
