I'm bringing this issue up again. The cu= rrent Bitcoin DNS seed
infrastructure is unstable. I assume this is because of we're using a custom DNS implementation which is not 100% compatible. There have been
bugs in the past, like a case sensitive match for the domain name.

Current state (seeds taken from bitcoinj):

mainnet:

seed.bitcoin.sipa= .be =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0OK
dnsseed.bluematt.m= e =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0= OK
dnsseed.bit= coin.dashjr.org =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0SERVFAI= L, tried multiple ISPs
seed.bitcoinstat= s.com =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 OK=

testnet:

tes= tnet-seed.bitcoin.petertodd.org =C2=A0 =C2=A0 =C2=A0SERVFAIL, just from= Telefonica
testnet-seed.= bluematt.me =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0OK (= but only returns one node)

Note: Telefonica is one of Europe's largest ISPs.

I would try to improve DNS myself, but I'm not capable of writing C. My=
"fix" would be to reimplement everything in Java -- I doubt you g= uys
would be happy with that.
