Is Something Wrong With Facebook Right Now
The crucial problem that caused this failure to be so serious was a regrettable handling of a mistake problem. An automated system for validating arrangement worths ended up triggering far more damages than it fixed.
The intent of the computerized system is to check for setup values that are void in the cache and also change them with updated values from the relentless store. This works well for a transient issue with the cache, but it doesn't function when the relentless shop is void.
Today we made a modification to the persistent copy of a setup worth that was interpreted as invalid. This meant that every customer saw the void value and also tried to fix it. Since the repair involves making a query to a cluster of data sources, that collection was swiftly overwhelmed by thousands of thousands of questions a 2nd.
To make matters worse, each time a customer obtained an error attempting to query among the data sources it translated it as a void value, and deleted the matching cache trick. This implied that also after the original trouble had actually been fixed, the stream of queries continued. As long as the databases fell short to service some of the demands, they were creating a lot more demands to themselves. We had gone into a responses loophole that didn't enable the databases to recuperate.
The method to quit the comments cycle was rather agonizing - we needed to stop all website traffic to this data source cluster, which suggested turning off the website. As soon as the databases had recuperated and also the origin had actually been fixed, we gradually allowed more people back onto the website.
This got the site back up and also running today, as well as in the meantime we've turned off the system that tries to deal with configuration worths. We're exploring new styles for this arrangement system following style patterns of other systems at Facebook that deal even more gracefully with responses loops and also short-term spikes.
We apologize once more for the website blackout, and we want you to recognize that we take the efficiency and also dependability of Facebook extremely seriously.
