I had similar results:

]$ dig any mesanetworks.net

But did get an A record after removing the "any" option, and repeating
the query:

Perhaps something IS wonky on their network.  I had the same results on
querying more than one DNS server, here.  The first attempt to "dig any
mesanetworks.net" doesn't work, nor does repeating it.  But, do a "dig
mesanetworks.net" (without the "any" option), and you get an A record
returned, and any query after that works, too.

NB:  There's also a change in the values written before "IN" on
subsequent queries. 

<http://www.dnsreport.com/tools/dnsreport.ch?domain=mesanetworks.net>
shows some errors.  Note that some warning are less important than
others.
