And the fix of course is to have one or more servers that aren't served by
anycast - then if anycast announcement fails at least there is a slim chance.
You can have too much of a good thing.
UltraDNS also serve some UK domains, but in addition to the pre-existing
servers - that seems to work well. Before this the UK domains were reliable,
but not well monitored (well not by the people who should have ;), although I
think the change probably reflected more professional management of the
relevant UK domains of which bringing UltraDNS in was probably only part, as
they also resolved other potential issues around the same time (and stopped
having servers go lame all too often).
Anyway I noticed that UltraDNS servers no longer return broken delegation
information - anyone know when this was fixed? I know I mentioned it to the
relevant ISOC representative in the vain hope the PIR would get something
done about it - and it has since happened - coincidence?
So I think PIR and UltraDNS seem to be making progress, but the failure of an
'anycast only' service was foreseeable I believe - so should have been
allowed for in design. Although I thought they would see more regional
failures, and so change the design before a more general failure.
