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At 6:28pmPDT, we retained an out-of-date DNS record during a routine infrastructure change.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.

On August 28, 2018 between 10:15amPDT and 10:59amPDT, Slack experienced a 44-minute outage where all users were unable to establish new connections to the Slack service. Users who were already connected to the service were able to remain connected during this time.
A configuration change at 10:15amPDT accessed incorrect settings and prevented service access for new connections. We reverted the configuration change at 10:59amPDT and new connections to the service were able to resume. We called the all clear at 11:23amPDT.
We are currently hard at work to scope preventative measures to ensure this does not happen in the future.
