Many major websites and services including ours were unreachable for a period Friday afternoon due to issues at Cloudflare’s 188.8.131.52 DNS service. The outage seems to have started at about 11:15 SAST and lasted for about 25 minutes before connections began to be restored. Google DNS may also have been affected.
Update: Cloudflare at 11:46 says “the issue has been identified and a fix is being implemented.” CEO Matthew Prince explains that it all came down to a bad router in Atlanta:
Details on how we caused an 23 min outage for~50% of @Cloudflare's network today. The root cause was a typo in a router configuration on our private backbone. We've applied safeguards to ensure a mistake like this will not cause problems in the future. https://t.co/iHQTiJ8O5J— Matthew Prince ? (@eastdakota) July 18, 2020
