Is There Something Wrong With Facebook Right Now
The essential imperfection that caused this interruption to be so severe was an unfortunate handling of a mistake problem. An automated system for validating configuration worths wound up creating far more damage than it dealt with.
The intent of the automated system is to check for setup values that are void in the cache and also replace them with upgraded values from the persistent shop. This functions well for a transient trouble with the cache, but it doesn't function when the consistent shop is invalid.
Today we made a change to the relentless copy of a setup value that was taken void. This indicated that every customer saw the void worth and tried to repair it. Since the fix involves making an inquiry to a collection of databases, that collection was rapidly bewildered by hundreds of thousands of queries a 2nd.
To make issues worse, every time a client obtained an error trying to inquire among the data sources it interpreted it as an invalid worth, and deleted the matching cache key. This suggested that also after the initial trouble had been repaired, the stream of questions proceeded. As long as the databases fell short to service a few of the demands, they were triggering a lot more requests to themselves. We had actually gone into a comments loophole that really did not permit the data sources to recoup.
The way to stop the comments cycle was quite unpleasant - we had to stop all web traffic to this data source cluster, which meant switching off the website. Once the data sources had recuperated as well as the root cause had actually been repaired, we slowly allowed more individuals back onto the site.
This got the site back up as well as running today, and in the meantime we've turned off the system that attempts to remedy configuration worths. We're exploring brand-new layouts for this arrangement system adhering to layout patterns of other systems at Facebook that deal even more beautifully with responses loopholes as well as transient spikes.
We say sorry once again for the site outage, as well as we want you to know that we take the performance as well as reliability of Facebook very seriously.
