Is Something Wrong With Facebook Right Now
The key problem that caused this interruption to be so extreme was a regrettable handling of an error condition. An automated system for verifying arrangement values ended up creating far more damages than it fixed.
The intent of the computerized system is to look for setup values that are invalid in the cache and also replace them with updated worths from the persistent shop. This functions well for a transient issue with the cache, however 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 invalid. This suggested that every single customer saw the void value as well as tried to repair it. Since the solution entails making an inquiry to a collection of data sources, that cluster was quickly overwhelmed by numerous countless inquiries a 2nd.
To make matters worse, whenever a customer obtained an error trying to inquire one of the data sources it interpreted it as a void worth, and also erased the equivalent cache key. This indicated that also after the original issue had actually been fixed, the stream of inquiries continued. As long as the data sources fell short to service some of the demands, they were triggering even more demands to themselves. We had entered a responses loop that really did not enable the databases to recuperate.
The method to quit the comments cycle was quite agonizing - we needed to quit all web traffic to this data source collection, which suggested turning off the site. As soon as the data sources had recouped as well as the source had been taken care of, we gradually allowed even more individuals back onto the website.
This obtained the site back up and running today, as well as in the meantime we've shut off the system that attempts to remedy setup values. We're exploring brand-new styles for this configuration system complying with layout patterns of various other systems at Facebook that deal more with dignity with feedback loops and also transient spikes.
We apologize once again for the site failure, and we want you to know that we take the efficiency and also integrity of Facebook extremely seriously.
