Hello:

I'm wondering if anyone has had a similar problem with domains resolving inconsistantly on different ISP's.

I have a few domains registered with Enom, and the websites are on a dedicated server running redhat 7.2.

I use ComCast, and can resolve everything, all of the time. The same is true for Verizon. However, friends of mine using Earthlink and RCN can rarely get to the websites, and usually they get a 'Page Cannot Be Displayed' error.

I have contacted the all parties involved (host, registrar, isp's) and they all blame the other.

I have also run www.dnsreport.com when the site was not accessible (at my friends house) and seen no difference in the results from my own computer.

Has anyone seen this before?

Its DNS problem of ISP. Best way to cross check is ping the site from diff countries.
:D

Hi - the one way to make sure it is DNS is to also try accessing the site by its IP address, if it works for just IP then its DNS if it doesnt work for both then its routing.

Yep, i use Earthlink Cable, usually takes longer for it to resolve for me than my friend using Verizon DSL, but i still love Earthlink's SPEED :D

Thank you all.

I thought that the problem was on the IPS's end. Your feedback has been very valuable.

I had a problem that looked like an ISP problem, but infact I don't think it was.

Have you tired adding A entries for the namerservers the domains are on?

Yes, I 99% sure that my DNS settings are correct for the domain.

What is the domain? I might be able to diagnose the problem. Too many people are quick to blame the ISP experiencing the problem when more often than not, the problem is a DNS misconfiguration on the host's end.

Very often, domain resolving sometimes and sometimes not is a classical symptom of stale nameservers [i.e you may have 3 nameservers but only 2 have been updated with the latest zone records]

As Toasty said, if you give out the domain some one will help :)
