Code search experiencing degraded performance

This incident has been resolved.

We have identified a cause for the latency and timeouts and have implemented a fix. We are observing initial recovery now.

Customers using code search continue to see increased latency and timeout errors. We are working to mitigate issues on the affected shard.

Elevated latency and timeouts for code search is isolated to a single shard experiencing elevated CPU. We are taking steps to isolate and mitigate the affected shard.
