Between February 27, 2026, 11:50 UTC and February 28, 2026, 17:40 UTC, Akamai observed degraded performance, intermittent connectivity issues, and packet loss affecting Edge Delivery and Cloud services for customers in India. The issue impacted multiple Edge locations and connectivity to Mumbai and Chennai data centers. The most significant impact occurred around 12:20 UTC on February 27, with a second window of disruption in the Mumbai region between 19:45 UTC and 21:00 UTC. A recurrence was identified on February 28, 2026, at 09:17 UTC. The recurrence was partially mitigated by 09:46 UTC and fully resolved by 11:08 UTC the same day.

The root cause was a chain of unexpected subsea cable outages that occurred during repair work by the third-party network provider, resulting in intermittent disruptions to internet traffic between India and Europe. During the event, traffic was rerouted through unstable alternate paths by the third party provider, resulting in packet loss and congestion. Additionally, isolation of a key network point prevented effective traffic management, leading to service interruptions.

Akamai took several actions to mitigate the impact, including suspending the traffic to the affected Edge locations, temporarily removing traffic from the affected ISP provider link, and closely monitoring the platform for stability. Once the third-party provider restored normal routing, Akamai removed temporary mitigations and confirmed service stability.
The incident was fully mitigated by the third party provider at 15:34 UTC on March 3, 2026, after no further recurrences were observed.
