Cloudflare suffered a massive outage that affected many sites that it services. The company said it is aware of "issues" in some regions and announced that an investigation into the incident is ongoing.
Several internet sites went down due to the outage, including Discord, Shopify, Feedly, Politico and League of Legends, according to DownDetector.
The company announced that the investigation on "Cloudflare Resolver and our edge network in certain locations" is ongoing. Later, Cloudflare announced the issue had been identified, and stated that the outage was not the result of an attack.
"It appears a router on our global backbone announced bad routes and caused some portions of the network to not be available. We believe we have addressed the root cause and are monitoring systems for stability now", the company said in a statement.
