We will perform a router upgrade maintenance for the Cogent network from June 9, 2026, 10:00 AM to 12:00 PM PDT, Los Angeles time. This corresponds to June 10, 2026, 1:00 AM to 3:00 AM Beijing Time.
During the maintenance window, all Cogent-related services will be affected and may become indirectly unavailable. Temporary connection interruption, higher latency, or routing instability may occur. The affected IP ranges include Cogent service IPs starting with 38. / 154. / 149.
The reason for this maintenance is a router upgrade. Services will recover automatically after the maintenance is completed. Thank you for your understanding.
