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.
“Redundancy can help with certain things like a complete system failure, but it doesn’t help with a virus or software bug because it can replicate it, so redundancy can’t help here,” he stated.
A tool worm shouldn’t have affected Instagram and Messenger, however Enderle figures that the issue was once associated with a shared-code factor, and no matter it was once that failed used the similar code or a by-product of that code, so it replicated throughout all products and services. “At the very least they should have firewalled the services to avoid something like this,” he stated.
Still, Enderle thinks one thing else occurring right here as a result of at the present time, an eight-hour outage shouldn’t final this lengthy except you’re beneath assault, and Facebook stated it was once now not beneath assault. “They should have rolled back whatever it was in minutes. It’s not like they are a novice company. This should not have happened,” he stated.
And given the consider problems Facebook has had, it’s in the most efficient pursuits of the corporate to come back blank, if just for the sake of its advertisers. Most people simply went on with our day.
