Cloudflare Maintenance Causes Temporary Network Disruptions

Cloudflare stated that “scheduled maintenance is currently in progress” and that it will “provide updates as necessary.”

Traffic from the Chicago location may be rerouted during this period. This could result in a “slight increase in latency” for users in the affected region.

Cloudflare also said some customers may experience temporary service changes. It warned that PNI and CNI customers should prepare for traffic to fail over to other locations, as “network interfaces in this data center may become temporarily unavailable.”

No service incidents "beyond the planned maintenance" were reported at the time of the update.
