Cloudlfare, an internet service provider responsible for various functions, went down Sunday morning, taking down many websites, including some crypto sites.

The company confirmed in a tweet it experienced issues around 9:24 am Eastern time caused by a third-party transit provider. Network stability returned around 11 am though Cloudflare said it is still monitoring for other potential problems. In a statement emailed to Cointelegraph, Cloudflare chief technology officer John Graham-Cumming said:

“Today we saw a widespread Internet outage online that impacted many multiple providers. This was not a Cloudflare-specific outage. Level 3/CenturyLink was responsible for an outage that affected many Internet services, including Cloudflare. Cloudflare's automated systems detected the problem and routed around them, but the extent of the problem required manual intervention as well.”

A large majority of the internet uses Cloudflare. News reports noted several popular websites went down following Cloudflare’s network issues, including streaming site Hulu and cooperative gaming services PlayStation Network and Xbox Live.

Crypto websites were not immune. Bitfinex Chief Technology Officer Paolo Ardoino tweeted that the Cloudflare outage caused any connection issues to Bitfinex Sunday morning.


Cloudflare’s last outage made people question if crypto holders are truly decentralized. That outage reportedly affected Bitcoin transactions.
