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.

At this time the upstream provider has been able to correct the issue causing packet loss on some routes from the in-maa & in-bom-2 data centers into the US region and will now consider this incident resolved. If you continue to experience problems, please <a href="https://cloud.linode.com/support/tickets">open a Support ticket</a> for assistance.

We are continuing to work with our upstream provider to resolve the packet loss affecting some paths between the in-maa and in-bom-2 data centers and the US region. We will share further updates as progress continues.

Our team has identified the cause of packet loss to our US data centers. We are working with our upstream provider to resolve this issue and we will provide an update as soon as the solution is in place.

Our team is investigating packet loss on some paths from the in-maa & in-bom-2 data centers into the US region. During this time, users may experience connection timeouts and errors with services traversing between India and United States regions. We will share additional updates as we have more information.

On 27 July 2026 at 3:30 UTC, Akamai observed an increase in errors when connecting to the Linode hosting database, primarily affecting Block Storage volume attachments. This resulted in host job failures and limited customer impact, with some users experiencing error messages and interrupted workflows. Elevated timeout rates were noted in logs for certain data center locations, coinciding with the incremental rollout of a new feature flag.

Initial investigation revealed intermittent packet drops from the database proxy to client hosts during the TLS handshake. The current theory suggests that a DDoS-protection limit related to path MTU packet too big ICMP messages was reached. When the proxy sent TCP packets with a large MTU, the expected ICMP messages were dropped by Dallas gateway routers due to exceeding the configured allowable rate. This caused database proxy TCP connections to timeout to Compute Hosts. The issue was triggered by the enablement of the new feature flag, which changed the routing path and removed MTU clamping before packets reached the gateways.

To mitigate the issue, Akamai rolled back the recent network change across affected Compute sites, starting at 20:50 UTC. As of 22:57 UTC, the rate of service restarts returned to pre-incident levels. Akamai is also planning a change to increase the allowable threshold for packet too big ICMP messages.

We haven’t observed any additional host jobs performance degradation issues, and will now consider this incident resolved. If you continue to experience problems, please <a href="https://cloud.linode.com/support/tickets">open a Support ticket</a> for assistance.

A fix has been implemented and we are monitoring the results.

We would like to update that after additional investigation, the impact would manifest in delayed and sometimes failed host jobs, which could include many different actions on Linodes and not only impacting attaching and detaching Block Storage volumes as we mentioned in our initial update, we have updated the title to reflect the updated impact. We are working quickly to implement a fix, and we will provide an update as soon as the solution is in place.

Our team has identified the issue affecting the Block Storage service in our data centers. We are working quickly to implement a fix, and we will provide an update as soon as the solution is in place.

Our team is investigating an issue affecting the Block Storage service in several data center regions. This issue largely impacts attaching and detaching Block Storage volumes. During this time, users may experience volume attach/detach hangs, timeouts and errors with this service. We will share additional updates as we have more information.
