Cloudflare reports multiple service issues

Cloudflare is dealing with 5 concurrent service issues — tracked live below.

By The Downtime · Aug 12, 2026 · 3:15 PM ·Updated 1 week ago

Cloudflare's Email Security service is experiencing a major incident affecting customers who use Spamhaus filtering in their downstream systems. The company is currently investigating the issue.

Cloudflare provides internet infrastructure and security services, including email security solutions, to businesses and organizations worldwide.

According to Cloudflare's status page, customers using Spamhaus for additional email filtering are rejecting messages originating from IPs in the 134.195.26.0/23 block. Cloudflare states this IP block should be allowed by all downstream systems to prevent the Email Security service from being treated as a mail originator. The company recommends that all Cloudflare Email Security customers disable Spamhaus filtering in their downstream systems while the investigation continues.

This is a developing story and we will update as more information becomes available.
