# **Incident postmortem: Email Sync Delay in Shared Inboxes** > Total downtime > > **6.5 hrs** > > Uptime in May 2026 > > **98.95%** > > Prior 12-month avg uptime of Hiver Services > > **≈ 99.98%** **What happened** On May 4, 2026, new incoming emails stopped appearing in Hiver shared inboxes for approximately 6.5 hours. The root cause was an unexpected and severe surge in message queue volume that overwhelmed a core infrastructure component — the Sync Engine — responsible for pulling emails from Gmail into Hiver in real time. Hiver's infrastructure is designed to handle up to 2× our peak traffic at all times. This is one reason we have maintained near-perfect uptime over the past two years. On this occasion, the surge exceeded even that ceiling, bringing the Sync Engine to a near-complete halt. **What we've done immediately** Our engineers have done a deep analysis of this incident. As a remediation step, we have added more elasticity to the message queues infrastructure so that it has more headroom for future surges. We are also committed to migrate additional queues incrementally and completely to the elastic queue infrastructure over the coming weeks. **What we're doing next** Beyond the immediate fixes, we are evaluating several longer-term improvements including faster detection-to-recovery workflows and more granular controls during abnormal volume conditions. We will keep sharing further details on this page as we make progress.
