1. updateOct 8, 2026, 4:00 AM UTC

   Status: Scheduled What is affected: We will apply a software patch to the web server/API that controls outbound dialing through our US SIP infrastructure. When: Tonight, Wednesday, October 7, 21:00–21:15 PT (04:00–04:15 UTC, Thursday, October 8). What to expect: Non-Campaign Outbound calls may briefly stall or fail to connect during the patch over a 5-10 minute period. We will validate for the remainder of the window to confirm calls are connecting normally and update this page when connectivity returns and maintenance is complete. Action needed: None.
