Issue Summary:

On August 28, 2019 at 10:01 a.m. PDT a change was released which unexpectedly prevented some customers from being able to create channels. Specifically, if the channel name included a hyphen or underscore.

An update was made to ensure channel names with such characters were validated correctly, and by August 29 at 12:33 p.m. PDT channel creation was functioning as expected once again.
