A Cloudflare outage, which began about 15 minutes ago, has hit several popular services including Discord, Omegle, DoorDash, Crunchyroll, Feedly, Zerodha, Medium.com, news outlet Register, Upstox and Social Blade. The internet infrastructure firm said it is investigating the “wide-spread” issue, but it’s unclear what all regions are impacted.

“Users may experience errors or timeouts reaching Cloudflare’s network or services,” said the firm, which suffered an outage in some parts of the world last week as well. John Graham-Cumming, CTO of Cloudflare, said on a Hacker News thread that it’s not a worldwide outage, but “a lot of places” are impacted. “Problem with our backbone. We know what. Rollbacks etc. happening,” he said.
