There was a problem yesterday with a major hosting service
where the DNS A-record propagation failed for a while. The end result, if you looked at “whatsmydns.net”
was that the sites were connecting in non-democratic countries (particularly
China) and some of eastern Europe, but in the west.
The problem was fixed in about two hours and was
intermittent. But it struck me that
something this could happen because of deliberate foreign hack. While sites, even individually owned, were
not reachable from the U.S. or some western countries, it sounds conceivable
hackers could have altered them in a proof-of-concept attack. I’m not aware that this really happened, but
the pattern is suspicious.
Many of these US-owned and based sites are supposedly banned
in China. It’s odd that only Beijing
could reach them for about an hour.
