What's Wrong With Facebook
The vital imperfection that caused this failure to be so serious was an unfortunate handling of an error problem. An automatic system for confirming setup values wound up creating much more damage than it fixed.
The intent of the automatic system is to check for setup worths that are invalid in the cache and replace them with upgraded values from the relentless store. This functions well for a transient trouble with the cache, yet it does not work when the relentless store is void.
Today we made an adjustment to the relentless copy of a setup worth that was interpreted as void. This implied that each and every single client saw the void worth and also tried to repair it. Since the solution entails making an inquiry to a collection of data sources, that cluster was quickly overwhelmed by thousands of countless questions a second.
To make issues worse, each time a customer got an error attempting to query among the databases it analyzed it as a void worth, and removed the corresponding cache key. This implied that even after the initial problem had been repaired, the stream of inquiries proceeded. As long as the data sources failed to service some of the requests, they were causing a lot more requests to themselves. We had actually gone into a comments loop that really did not allow the data sources to recover.
The way to stop the feedback cycle was fairly excruciating - we needed to stop all website traffic to this data source collection, which suggested turning off the website. Once the databases had recouped and also the root cause had been repaired, we gradually enabled even more people back onto the site.
This obtained the site back up and running today, as well as for now we have actually turned off the system that tries to deal with arrangement values. We're checking out new layouts for this arrangement system complying with style patterns of various other systems at Facebook that deal even more with dignity with responses loopholes and short-term spikes.
We ask forgiveness again for the website blackout, as well as we desire you to recognize that we take the performance and integrity of Facebook extremely seriously.
