for the online whois form http://www.dynadot.com/domain/search.html i get lots of .eu The connection to the central registry is busy; please try again later or .cn The central registry is down for maintenance; please try again later .com The central registry is down for maintenance; please try again later .com There was a problem connecting with the central registry; please try again later for .ws as well (the above were pasted from some queries i just did)
maybe a problem with limiting your whois queries and not balancing them? ive built an online dns tools website and it has whois as well, im balancing the whois queries from 6 ips to make sure i have a higher limit and wont get filtered off for too many queries, maybe something similar here as well, but im sure as a dns provider you should have some dedicated access to that, but the errors..
well im sure they do like i said "..but im sure as a dns provider you should have some dedicated access to that" but its happening too often for a month or so now, and everyday if i run a few queries i see a few of those errors and need to repeat a couple of times until it works again.. i just posted this for info dont shoot me :-)
Sorry for the connection problems. Recently we were having problems with CN and EU searches.
The reason is we only get 2 connections from the central registry. So often we run out of connections for CN and EU. We have made some code modifications recently to better use these connections. Hopefully it will help.
