Resolved
On September 21, 2026, starting at approximately 16:10 UTC, Akamai observed degraded DNS resolution performance affecting a subset of Linode instances within the London (`LON1`) region. Platform-wide DNS resolution remained functional, and no other regions were affected.
The disruption occurred during a drive transplant of a compute host at the London (lon1) data center, which temporarily took a customer-facing DNS resolver offline. Due to a software logic flaw, customer workload configurations deployed in the last year across the region were disproportionately reliant on this single resolver, causing DNS failures when it became unavailable.
At 21:45 UTC, engineering teams deployed an emergency configuration update to rebalance and reorder active DNS resolver assignments in the region, returning DNS query performance to baseline levels. Post-remediation monitoring confirmed stable operations across `LON1`.
Long-term engineering updates are currently being deployed to ensure provisioning utilities dynamically assign distinct, active DNS resolvers across all regions to prevent recurrence.
This summary reflects our current understanding of the incident based on available details. Our investigation remains ongoing, and findings may be updated as further information is reviewed.
