How did Facebook go down despite multiple data facilities?

The Mercury retrograde kicked in giant time on Wednesday as Facebook suffered an 8 hour-outage that still affected Instagram and Facebook Messenger.

No one was once believed to be harmed; a couple of may have even had offline interactions with different human beings.

Facebook stated it wasn’t an assault, like a Denial of Service assault, and has since issued a remark attributing it to a configuration error.

“Yesterday, we made a server configuration change that triggered a cascading series of issues. As a result, many people had difficulty accessing our apps and services,” said Travis Reed, a Facebook spokesman. “We have resolved the issues, and our systems have been recovering over the last few hours. We are very sorry for the inconvenience and we appreciate everyone’s patience,”

The query for me is how may just an organization with redundant data facilities across the U.S., to not point out the world over, be taken down like this? All instructed it has seven data facilities within the U.S. Redundancy is meant to lend a hand save you this sort of drawback.

Well, now not precisely. In the case of a worm or running drawback, redundancy doesn’t lend a hand. In reality, it will possibly unfold the issue temporarily, notes analyst Rob Enderle.
