[Outages-discussion] [outages] Google DNS issue (maybe with CenturyLink)

[Ian Gallagher]

(Moved to -discussion)

CL/Google DNS Seems to have came back for me around 2021-08-15 04:19 UTC,
no issues since then until now.

During the outage, I didn’t notice any other issues, including to other
Google properties - only their public resolvers.
