[TriLUG] OT: Opinion about DNS service

[Brian via TriLUG]

Hi gang,

Lately I've been very disappointed with the dynamic DNS I've been 
getting from dynip, a Canadian company.  At least once a day, a script 
of mine that runs every 5 minutes gets an empty response to a lookup 
from one of their nameservers.

I managed to get through to their tech support folks (which wasn't 
easy...their own support e-mail system was also broken...), and their 
response was "the names[sic] servers are reloaded approx every 10 
minutes so it is possible to issue a query to a specific server and not 
get a response as the zones are reloading."

All my script does is "dig +short cheetah.dynip.com A", so the "specific 
server" is whatever the resolver decided to use to get the answer.

Is this just an unavoidable window-of-opportunity thing, or should I be 
irritated?  Anecdotally, I have yet to observe a failure when checking 
dynamic DNS records hosted by Hurricane Electric...
