Cloudflare Worldwide Outage Caused by Bad Software Deployment

Cloudflare Worldwide Outage Caused by Bad Software Deployment

Cloudflare experienced a worldwide outage today for about 30 minutes, with network performance issues that brought down a multitude of websites and web services all around the world, and triggered “502 Bad Gateway” errors.

While various speculations said that the provider of content delivery network and DDoS mitigation services was being under attack, Cloudflare’s John Graham-Cumming says that the 502 errors seen by visitors of Cloudflare sites were actually caused by a spike in CPU utilization on the provider’s network.

“This CPU spike was caused by a bad software deploy that was rolled back,” adds Graham-Cumming. “Once rolled back the service returned to normal operation and all domains using Cloudflare returned to normal traffic levels.”

“This was not an attack (as some have speculated) and we are incredibly sorry that this incident occurred,” also stated Graham-Cumming in a post on the company’s official blog.

Cloudflare was not under attack

The Cloudflare blog post confirms what the company’s CEO said on Twitter during the network outage:

Prince also tweeted about the network issues experienced by Cloudflare during the incident, reassuring customers that the team was “working on getting to the bottom of what’s going on.”

The incident report regarding today’s HTTP 502 errors experienced by customers was updated by the Cloudflare team one hour after the initial update and 30 minutes after the network performance issues were fixed, saying that:

Major outage impacted all Cloudflare services globally. 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.

Seven minutes later, Cloudflare changed the status of the incident report to Resolved and added the following message: “Cloudflare has resolved the issue and services have resumed normal operation.”

Second Cloudflare outage in week

This is the second time within a week that Cloudflare experienced a network outage, although the BGP route leak it went through on June 24 was caused by Verizon and Noction.

According to Cloudflare’s CEO, the BGP route leak was quite hard to fix given that Cloudflare’s team was not able to contact the Verizon NOC during the outage.

Seeing that more than 16 million websites use Cloudflare’s DDoS mitigation, performance enhancement, and various other services, Cloudflare outages usually have a large impact on the Internet as a whole.
