[dns-operations] .uk validation failure

[Anand Buddhdev]

In case anyone is having problems looking up names in .uk, and doesn't
know why, here is the reason:

I lookup failures on our resolvers last night, and after I noticed that
the ZSK in our cache was different from the one served by the .uk
servers, I concluded that something had gone wrong with ZSK roll-over,
so I flushed our caches.
