Reduced cache performance for Compute services

We have identified the cause of reduced cache-hit ratio and elevated origin load affecting a subset of Compute customers using caching, and have deployed a fix. The fix is being rolled out gradually across affected sites and cache nodes, timed to off-peak windows to minimize any additional disruption. Some locations have already completed the rollout; others remain in progress. We are actively monitoring recovery and will provide another update as the rollout completes.
