I'm sorry if this is in the wrong forum. I've been a reader here for a long time, but I'm not a regular.
Here's my situation. I'm a designer/programmer. I have a reseller account with a hosting business that has plenty of good reviews here. I've been VERY happy with them for about a year.
I don't offer hosting, but i do sell hosting to clients who pay me for site design or programming. I host about 10 clients right now.
About a month ago, some of the client sites started going down, while other sites on my account had no issues. It seems random, with very little consistency.
I payed more attention and realized that some of the sites were going down for hours at a time, at random times. Not all of the sites on my reseller were affected, but there were at least 5.
My first support tickets relating to the random down times were shrugged off by the host, but after some nagging they told me that my dns zones were misconfigured (something about stealth nameservers). It was odd that every site worked fine for the last year and just NOW started having problems - but they're the experts.
My nameserver issues:
some sites were pointing to ns1/ns2.mydomain.com
some were pointing to noc1/noc2.mydomain.com
others were pointing to dns1/dns2.adifferentdomain.com
I had these nameservers set up in godaddy (my registrar). They've been like that for a year with no issues.
Thinking i'd fix them, i changed all the domains to point to ns1/ns2.mydomain.com.
I also used WHM and edited the dns zones for those accounts and made sure they all had the same nameservers.
Its been a couple weeks since i've fixed everything, and sites are STILL having issues.
My host insists that its a godaddy issue, but I can't understand how some sites work and some don't (when they have the same nameservers and IP)
I no longer know what to do.
