[outages] [External] Re: 4.2.2.2 down in LA area

[Hunter Fuller]

Additionally, configuring one DNS server is a bad idea. I’m not sure if
4.2.2.2 is anycasted, but 4.2.2.1 through 4.2.2.6 exist and all work, so if
you are a Lumen customer and want to use their resolvers, it’d be prudent
to configure any two of those.

In other words, I mean this as gently as possible, but one of six redundant
servers going offline is not what I’d call an “outage.”
