Website is Unreachable using certain ISP
I have a problem with my website, there are times that my is unreachable through the domain name but can be viewed using the IP, however, if browsing the site using a different ISP it can be viewed.
How do you solve problems?
try using traceroute to see how close to the remote network you can get.
The website is
www.pic-link.com. Im actually not experiencing it right now but there are times when I do. And the following day it just works again or a couple of hours after.
I see where the problem is. The NS1 for your domain is not responding. Here are the results from the test I did:
Searching for A record for pic-link.com at a.root-servers.net: Got referral to E.GTLD-SERVERS.NET. [took 58 ms]
Searching for A record for pic-link.com at E.GTLD-SERVERS.NET.: Got referral to vs1.astang.com. [took 101 ms]
Searching for A record for pic-link.com at vs1.astang.com.: Error: Couldn't resolve DNS server name/IP [vs1.astang.com].
An error occurred: Couldn't resolve DNS server name/IP [vs1.astang.com].
All this time, the NS2 is responding fine by getting the A records for your domain. So when a visitor types in the URL and if the DNS of the ISP queries the NS2, your site will fail to load.
is it adventageous to add a tertiary name server for redundancy or is it all a matter of the the qualifying hosts operating stability ?
Well I just kinda added the ns1.astang.com and ns2.astang.com just recently after the problem. What I did is on the other server (thats the ns1 and ns2) I am on, I added pic-link.com and have the IP pointed to the real server where pic-link resides. the real server where piclink is at NAC and the second server is at GNAX. I had checked my dns settings and dnsreport and it passes. I hope this is the best solutions I could get.
I don't think it's a good solution.
So what can you suggest? In the other server I added an A record so that if ever vs1 and vs2 nameserver fails the server could still be reached.
