Linode (Akamai) outage on 2026-07-31: Upstream Loss - Some Paths (in-maa/in-bom-2 to US Region)

On July 31, 2026, at approximately 10:00 UTC, Akamai observed intermittent network losses affecting compute users accessing US locations from our India sites \(MAA and BOM\). Customers’ services in North America, particularly the Miami data center region, experienced increased latency, intermittent connectivity issues, slower data transfers, and difficulty reaching certain applications or services. Performance was unstable, with periods of normal operation followed by disruptions. To address the issue, Akamai applied a deny-all policy to the impacted upstream provider transit link, redirecting traffic around the impacted routes. Despite this mitigation, ongoing IPv6 losses occurred due to congestion between two alternative upstream providers, impacting some users. One provider acknowledged a bottleneck in the Asia region, and the alternate provider worked to reroute traffic away from affected links.  The initial impacted service provider confirmed that two fiber cuts in Mexico caused congestion on the impacted routes. One of these fiber cuts was resolved at 23:43 UTC on July 31, 2026, and no further issues were observed following this mitigation.  This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing and any information herein is subject to change.
