    We're experiencing low host capacity in GRU. Creating or starting Machines in the region may fail at this time. Remote builders in GRU are also impacted. We're actively provisioning additional capacity. As a temporary remediation, customers may consider creating resources in EWR or IAD.

Platform Wide Rolling Host RebootsFly.io rebooted hosts fleet-wide over about 11 hours to mitigate kernel vulnerability PwnEscape (CVE-2026-99999). Machines and volumes on each host were unavailable for 15-20 minutes, with multiple hosts per region down at once. Managed Postgres saw elevated primary-standby switchovers and some clusters stayed offline. Restarts finished and the platform was declared normal, though a few hosts remained degraded.AI-graded

    We will be imminently applying rolling restarts across all hosts in our fleet for a critical maintenance. Customer Machines, volumes, and MPG cluster instances on each host will be unavailable while their host reboots. Each host will be unavailable for 15 - 20 minutes during the restart, and multiple hosts in a region may be down at once. Users should expect a period of downtime or disruption for their apps, especially if they are running on a single machine. We are aiming for the highest possible uptime during the rollout, while ensuring this is completed quickly. We will provide a further update once we begin the restart process.

    Host restarts are continuing in phases across all regions. Only a subset of hosts in each region will be down at each time.

Upstash unavailability in FRA regionFrom about 12:00 to 13:05 UTC, some clients got connection timeouts to Redis databases hosted in or routed through the fra and gig regions. A planned Upstash rolling upgrade left replicas out of service and returned them to routing before they were ready. Fixes planned include safer replica return and upgrade checks.AI-graded · regional

    **Impact** From about 12:00 to 13:05 UTC, some clients got connection timeouts to their Redis databases. Affected were databases hosted in fra or gig, and clients whose connections were routed through fra or gig, even if their database is hosted in another region. **What happened** During a planned rolling upgrade, replicas in fra and gig did not finish draining and were left out of service. They were returned to Fly routing before they were ready to accept connections. Connections routed to them then timed out. **What we're changing** • We will be adding tooling to return a replica to service safely after maintenance. • We will be adding safety checks to our upgrade process. • We will make the upgrade procedure more resilient to errors like this one.
