Degraded SIP Connectivity in India

Summary On June 2, 2026, a subset of users placing or receiving SIP calls through LiveKit Cloud's India region experienced call failures between 12:00 and 12:40 UTC. During a routine maintenance, both of our SIP-serving regions in India were temporarily disabled in error. With no SIP capacity available in India, traffic was routed to our Dubai region, where outbound calls to Indian numbers were rejected at the destination for region-pinned projects and inbound calls targeting India-specific endpoints failed to connect. We mitigated this by re-enabling SIP in the India region and restoring normal capacity. Timeline (UTC) 12:00 — Both India SIP regions disabled during maintenance; start of measurable customer impact 12:40 — India SIP regions re-enabled; customer impact ends Root cause The incident was caused by an operational error during planned maintenance. LiveKit operates three data centers in India, two of which serve SIP traffic. While disabling regions as part of our routine maintenance, the operator disabled both SIP-serving data centers, believing the third data center was also running SIP and would continue to carry customer traffic. Because the third data center does not serve SIP, this removed all SIP capacity in the India region and forced traffic to our Dubai region, where it could not complete region-pinned calls. Resolution Once we identified that India SIP capacity had been removed, we re-enabled SIP in the affected regions, which restored normal inbound and outbound calling in the region.
