Cloudflare has announced that its Detroit data center will undergo scheduled maintenance on December 5, 2025, from 5:00 PM to 9:00 PM. During this period, traffic may be rerouted, potentially causing minor network latency for users in the affected area. Customers using PNI/CNI services should be aware that traffic might be diverted to other locations, and network interfaces in the Detroit data center could be temporarily unavailable.
