Millions of websites go down across the internet after massive suspected Cloudflare outage (now fixed)

Recommended Posts

Cloudflare has gone down around the world and vast numbers of websites have gone down with it.

The company provides cloud computing services to millions of people, meaning that a lot of websites are not accessible.

 

One of these is Down Detector, which tracks outages, meaning people can’t even see if the website they want to visit is working or not.

 

The chat service Discord has also stopped working as well as a number of other prominent pages.

 

Matthew Price, Cloudflare CEO, tweeted: ‘Aware of major @Cloudflare issues impacting us network wide. Team is working on getting to the bottom of what’s going on. Will continue to update.’

 

One person tweeted: Cloudflare, possibly the largest internet/networking company in the world doesn’t have any kind of automated visibility on downtimes. does that not concern anyone?

 

‘Half their network is down and their status page says “all systems OK!’ they claimed.

 

The outage appears to have started in the past hour. Unable to check Down Detector for updates, people took to Twitter in a quest for answers.

 

‘Sure is great that when Cloudflare goes down it takes half the Internet with it,’ one person wrote.

 

 

Another roared: ‘Typical illustration of how bad the internet is centralized nowadays: Cloudflare is down, most websites & services being disrupted by this.’

The outage caused problems with the cryptocurrency website Coindesk, which tweeted: ‘ Due to a Cloudflare outage, we’re getting bad data from our providers, which is showing incorrect crypto prices.

‘Calm down everyone, Bitcoin is not $26.’

 

The outage appears to have been resolved now.

Price added: ‘Appear to have mitigated the issue causing the outage. Traffic restored. Working now to restore all services globally. More details to come as we have them.’

Cloudflare goes down, outage caused by "network performance issues"

 

https://s7d6.turboimg.net/sp/13668093eb5438b94e9f02a2f39d950a/ThinkstockPhotos-133303794.width-358.jpg

 

For the second time in two weeks, say hello to 502 Bad Gateway

 

Network services provider Cloudflare is down for the majority of its users, bringing services like Discord, Marketo, Down Detector and DigitalOcean offline.

 

The full cause of the outage is unknown, with Cloudflare's support page simply noting: "Cloudflare is observing network performance issues. Customers may be experiencing 502 errors while accessing sites on Cloudflare.

 

"We are working to mitigate impact to Internet users in this region."

 

CEO Matthew Prince tweeted: "Aware of major Cloudflare issues impacting us network wide. Team is working on getting to the bottom of what’s going on. Will continue to update."

 

Update, 14:15 UTC: "Cloudflare has implemented a fix for this issue and is currently monitoring the results.

 

"We will update the status once the issue is resolved."

 

Update, 14:45 UTC: Services appear to be resuming. Cloudflare notes, however, that "Cloudflare Analytics processing is running behind. This affects timely delivery of customer data.

 

"We are working to mitigate impact. "

 

Update, 14:50 UTC:

Cloudflare explains: "We saw a massive spike in CPU that caused primary and secondary systems to fall over. We shut down the process that was causing the CPU spike. Service restored to normal within ~30 minutes. We’re now investigating the root cause of what happened."

 

Update, 14:57 UTC:

"Cloudflare has resolved the issue and services have resumed normal operation."

 

Déjà vu

A similar problem happened just last week, when Cloudflare was unavailable for roughly 1hr 42m.

 

That time, Cloudflare noted that the downtime was not its fault: "Earlier today, a widespread BGP routing leak affected a number of Internet services and a portion of traffic to Cloudflare. All of Cloudflare’s systems continued to run normally, but traffic wasn’t getting to us for a portion of our domains. At this point, the network outage has been fixed and traffic levels are returning to normal.

 

"BGP acts as the backbone of the Internet, routing traffic through Internet transit providers and then to services like Cloudflare. There are more than 700k routes across the Internet. By nature, route leaks are localized and can be caused by error or through malicious intent. We’ve written extensively about BGP and how we’ve adopted RPKI to help further secure it."

 

In a blog post for DCD, Alex Henthorne-Iwane, of network monitoring company ThousandEyes, explained: "Route leaks happen fairly regularly. Routing is complicated. Humans make configuration errors, as we saw with the MainOne Nigerian ISP route leak that caused the global rerouting of some of Google’s traffic. And sometimes automation systems can trigger service disruptions, as we saw in the recent Google outage."

 

Both ThousandEyes and Cloudflare pointed the blame at Verizon. Henthorne-Iwane said: "The fact that Verizon accepted and propagated a huge set of leaked routes from a downstream enterprise eyeball network turned what could have been an isolated issue into a significant outage.

 

"There has been some heated commentary on this topic from Cloudflare and other Internet observers, who have commented that Verizon should have caught this issue with one of multiple possible filtering mechanisms. Those critiques are more than fair on their face."

 

This time around, however, it is unclear what was the cause of the outage.

 

Rather widespread
