[Outages-discussion] [outages] [External] Re: 4.2.2.2 down in LA area

[Jay Ashworth]

Indeed, there are quite a number of publicly accessible - and publicly intended - customer resolver DNS servers not directly associated with access networks.

The six DNS resolvers in the former gte/bbn 4/8 Network are not intended as publicly accessible servers, and indeed <admin>are not a suitable topic for outage reports on this list</admin>.

Suitably vetted outage reports about such resolver servers which are intended for public use probably are. If you don't know what constitutes suitable vetting for such a report, you probably shouldn't make one. :-)

Who does 9/8 belong to these days, Patrick?

Cheers,

Second, while it is publicly available for DNS, it is first and foremost a server for Level 3 customers. What they do with it and how available it is outside the network is not guaranteed. YMMV.
