1. IL-0564 Linode's Miami, Milan and Sao Paulo data centers had packet loss as traffic moved onto congested alternate paths

   Linode2025

   Symptoms

   Customers using Linode's US-MIA (Miami) and IT-MIL (Milan) data centers saw packet loss and brief performance problems on 14 September 2025 from 17:42 to 18:43 UTC. BR-GRU (Sao Paulo) had the same packet loss on 15 September 2025 from 01:44 to 04:22 UTC.

   Packet loss

   Trigger

   A gradual increase in prefixes pushed the routing between the core router and the edge router past the maximum number of permitted prefixes.

   Root cause

   Capacity exhaustion

   Component

   BGP routingBackbone network (WAN)

   Contributing factor

   –

   Remediation

   • Raised the prefix limit on all the data center routers

   Action items

   • Raise the thresholds of the sessions between Akamai's backbone and the data center ECOR routers
   • Improve the existing alerting and check its severity before limits are reached, with escalation to the right team for immediate action

2. IL-0563 Linode servers lost connectivity in all data centers as route servers built incomplete BGP route tables

   Linode2025

   Symptoms

   At about 16:38 UTC on 17 March 2025, internal alerts fired across multiple Linode data centers because various servers had been unreachable for an extended period. At the same time customers began reporting problems with several products.

   Network unreachableService outage

   Trigger

   A release of Akamai Compute's internal backend API component was rolling out, and during the rollout the API gave inconsistent responses to the route servers.

   Root cause

   Faulty deployment

   Component

   BGP routingNetwork control plane (SDN)

   Contributing factor

   Partial rollout

   Detection

   Internal alerts fired across multiple data centers showing servers unreachable for an extended period, and customers reported problems with multiple products at the same time.

   Remediation

   • Restarted the route servers in all data centers in phases, starting with the most affected regions

   Action items

   • Hold backend API releases until there is a better way to make sure route data for route servers is contiguous
