After: <b>We are currently investigating elevated build queues on Bitrise. Some users may experience longer-than-usual wait times for builds to start, as queued jobs take longer to be picked up.</b>
<b>What’s happening?</b>
<b>Services:</b>
Build start times and queue wait times; build execution itself remains normal once a worker is allocated.
<b>Scope:</b>
Builds on M4 Pro machines
<b>Severity:</b>
SEV-2
<b>What we’re doing?</b>
Our Engineering teams are actively investigating causes, reviewing worker pool utilization, autoscaling events, recent deploys, and any upstream provider issues. We are analyzing metrics and logs to identify bottlenecks like unusually high build volume, throttling from third-party providers, etc. We are working on immediate actions to remediate this issue. We will perform validated mitigations as soon as they are determined safe.
<b>When will the next update be available?</b>
