Internet users on Tuesday have faced severe problems accessing thousands of websites because of a glitch with the website security firm Cloudflare.
Many people have been seeing “502 errors” the US cybersecurity firm said.
A 502 error code means that the internet server has received an invalid response from the other server it is trying to contact.
Matthew Prince, the company’s co-founder and chief executive said on Twitter, “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.”
Within 20 minutes Prince tweeted, “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.”
Chat service Discord and CoinDesk a cryptocurrency firms were both affected, CoinDesck chief executive said they had suffered a distributed denial of service (DDoS) attack, meaning the servers were flooded with traffic.
