I cannot connect to zpool from one of my farms (one external IP):
Pinging sha256.mine.zpool.ca [198.50.152.135] with 32 bytes of data:

However I can do it from another IP in another farm. Everything is OK?
do a traceroute; see where the hop goes stale....
try a static dns like 1.1.1.1....
Some ideas =)
