Subject Re: [Hosting] DNS outage (currently temporarily resolved)
Date Tue, 17 Sep 2019 22:31:05 GMT
We have updated our configuration management to account for the changes in
Bind and will be deploying the change at 4pm PDT (2300 UTC) today (in just
about 30 minutes). Unfortunately, this may cause a momentary outage on a
specific DNS server when we push the update. To minimize the impact, we'll
be pushing this update one server at a time and confirming the fix is
working properly.
