Cloudflare scheduled maintenance in EWR (Newark) datacenter on 2026-09-02
Cloudflare will perform scheduled maintenance in its EWR (Newark) datacenter on 2026-09-02 between 05:00–09:00 UTC; traffic may be rerouted and PNI/CNI network interfaces could be temporarily unavailable.
What changed
Cloudflare announced a scheduled maintenance window for the EWR (Newark) datacenter on 2026-09-02 from 05:00 to 09:00 UTC; during the window traffic may be rerouted and some network interfaces could become temporarily unavailable.
Why it matters
Customers whose traffic normally transits the Newark location may see slight increases in latency or transient connectivity changes. Direct connections (PNI/CNI) to EWR should expect failover behavior for their interfaces during the maintenance.
Who is affected
Users served via the EWR (Newark) datacenter and customers with PNI/CNI links to that location are potentially affected. The announcement does not specify which services, customers, or geographic subregions will be impacted, so the exact scope and duration of user-visible effects are unknown.
What to do now
- Confirm whether your infrastructure uses the EWR (Newark) datacenter (check routing, POPs, and PNI/CNI attachments).
- For PNI/CNI customers: validate that failover paths are configured and tested so traffic will reroute away from EWR during the 05:00–09:00 UTC window.
- Monitor Cloudflare’s status page (the EWR maintenance entry) during the window for live updates.
- Subscribe to Cloudflare notifications via dashboard (email, PagerDuty, or webhooks) to receive direct alerts about this maintenance.
- Alert application and SRE teams of potential slight latency increases for end-users in the affected region and prepare on-call staff to investigate any anomalies.
