Meta Muse 团队已部署修复,提升定时任务与 cron 的恢复能力和可靠性,并加强了 VM 内 cron 系统的监控与告警。此前团队为提升底层模型扩大上下文窗口后的 KV cache 命中率、改进 VM 调度算法以减少部署停机、并在全集群部署新认证 token 格式,期间发生数次 SEV 故障,推理层无响应、VM 在部署期间长时间不可用。
Scheduled Tasks on @Muse - An update on reliability
We deployed a fix to Muse to improve scheduled task and cron recovery and reliability especially, and have hardened our monitoring and alerting of the cron systems in the VMs.
Over the last few days the Muse team has been deploying a few changes to:
Improve the KV cache hit rate after increasing the context window size of the underlying model
Improve our VM scheduling algorithm to reduce downtime during deployments
Deploy a new authentication token format across the fleet for more fine-grained access.
During these changes we had a few SEVs (outages) where the inference tier was unresponsive, and the VM scheduling resulted in VMs not being available for longer periods of time during deployment and being unresponsive to clients.
We observed after we recovered from these outages that several crons and scheduled tasks failed to resume / heal properly when the outage was done, resulting in several users receiving reports from their Muse that the crons have been failing for a while.
We apologise for this incident, and know how much this disrupts your flow especially since many users rely on muse to reliably deliver outcomes for them. We take these outages seriously, and are running a full audit of our recovery systems and tools, and are adding more dashboards and alerts so you can continue to receive the high quality service we want all users to have.
