For about a week I've been having trouble accessing a website I frequently visit from my laptop in my apartment. (The domain is http://www.irishgaelictranslator.com if it matters.) Symptoms are as follows:
- Whenever I try to access the site normally (i.e. in a browser) the connection times out.
- Trying to resolve the site name on DNS using
dig +showsearch +trace www.irishgaelictranslator.comends with the message "connection timed out; no servers could be reached".
digis able to retrieve the NS records for the domain, which specify the nameservers
ns2.irish-sayings.com.(18.104.22.168). It times out trying to connect to either of those servers.
- The IP address for
www.irishgaelictranslator.comis 22.214.171.124, and attempts to ping that IP address are unsuccessful. The connection times out.
- When running
traceroutethe trace reaches up to
sc-smv1461.servint.net (126.96.36.199)(step 21) with no problems or delays, and then I get just
* * *after that.
So far it just sounds like the server is down. But here's the weird thing: I have no problems accessing http://www.irishgaelictranslator.com from any other computer. I also have no problems accessing any other websites from my laptop. As far as I can tell, it's only the one particular combination of my laptop in my apartment and this one website that is causing problems. (I haven't tried taking my laptop elsewhere, but that's probably next on my list)
What sort of diagnostics can/should I run to try to figure out what's going on here? As mentioned, I've already tried
dig, and I've also fired up Wireshark during all three of these to see if it showed anything useful, but I haven't seen anything that signals a problem to me. (I'm not the greatest networking expert, I could be missing something) Is there anything else to do?
As the tags suggest, I primarily run Linux, but I do have Windows available to test with as well. (I have the same connectivity problems to the website when I'm running Windows, so it's not an operating-system-dependent problem.)
EDIT: The problem turned out to be that my IP address was blacklisted by the server's firewall. No idea how it got on the blacklist, but the site admin removed it and the connection works now. Anyway, even though my specific problem has been resolved, I'm still interested in any more suggestions as to tests I could have done to gather useful information.
