What Happened
Cloudflare is currently experiencing a major outage. We are currently investigating an issue where customers that use Spamhaus for additional filtering of email downstream from the Cloudflare Email Security service are rejecting emails from IPs in the 134.195.26.0/23 block. This IP block should be allowed for all customer downstream systems to avoid treating the Email Security service as an originator of mail. We recommend all Cloudflare Email Security customers disable Spamhaus filtering in downstream systems.
Web infrastructure and security company providing CDN, DDoS protection, DNS services, SSL/TLS encryption, and Zero Trust security for websites and applications. Teams that depend on Cloudflare may experience disruptions during this incident.
