Subject: Re: New website DNS issues
I get short timeframes when it works just fine. Most of the time DNS fails to get the address. Here's the DIG output for both success and failure:

Successful Lookup:

Failed Lookup specifying the Sequoia nameserver:

It looks like ns2.sequoia.net isn't responding reliably, and ns3.LuftHans.com doesn't always get queried unless an exhaustive search query is executed (I always got the successful run when using the +trace option).
