Incident

Some customers may experience trouble making Slack Calls from mobile

Technical Summary
On August 28th, 2018 between 6:28pmPDT and 9:24pmPDT, Slack users in the APAC region were unable to initiate a Slack call on a mobile device.

At 6:28pmPDT, we retained an out-of-date DNS record during a routine infrastructure change. This prevented Slack Calls from mobile devices in APAC from connecting with the up-to-date infastructure settings.

At 9:24pmPDT we manually removed the errant record and immediately resolved the issue. We’re currently working on preventative measures to avoid repeats of this scenario.
