Help please

Glenn · Sep 16, 2011, 12:51:19

If you are using the IDNet DNS, can you try this website please http://www.1914-1918.net/ yesterday it said it was not available when I tried at home, but was reported as up when I check with http://www.downforeveryoneorjustme.com/

Simon · Sep 16, 2011, 12:56:34

I just happened to have popped indoors, so tried it, and 'server not found', Glenn.

Ray · Sep 16, 2011, 13:00:20

Server not found here too, Glenn.

JB · Sep 16, 2011, 13:01:36

I don't know if it helps but the site loads perfectly here in Spain using Telefonica's DNS.

Steve · Sep 16, 2011, 13:32:08

I agree it's up and fine on OpenDNS still no go IDNet DNS.

Glenn · Sep 16, 2011, 13:39:47

OK thanks guys

Glenn · Sep 16, 2011, 14:24:33

Hi guys, hopefully this should now be working could you check please?

Ray · Sep 16, 2011, 14:35:55

Still not working for me, Glenn.

Lona · Sep 16, 2011, 14:40:20

Or me

Glenn · Sep 16, 2011, 15:26:20

Ray,

Brian has asked if clearing the DNS cache helps, could you try for me please? Just need to run ipconfig /flushdns from a dos prompt.

Ray · Sep 16, 2011, 15:39:56

Still the same, Glenn, I've even cleared the Browser cache as well.

Glenn · Sep 16, 2011, 15:48:35

Thanks Ray.

Glenn · Sep 16, 2011, 16:12:45

Couple of more things Brian has ask to check;

QuoteCan they set the DNS in the TCP/IP settings of their PC?

Also are they able to ping the site?

Support are able to access the site from their office

I can try when I get home, but if someone could answer the above questions it would be appreciated.

Rik · Sep 16, 2011, 16:19:38

I can't reach it or ping it, Glenn, and I've got DNS set in the TCP/IP settings.

Glenn · Sep 16, 2011, 16:23:25

OK thanks, I'll let Brian & Simon know.

Rik · Sep 16, 2011, 17:22:04

Still not working here, Glenn, after another DNS flush.

Glenn · Sep 16, 2011, 17:32:54

Simon did take a look at first but all follow up mails have been from Brian, I think he has now gone home, so it may have to wait until Monday.

Rik · Sep 16, 2011, 17:34:06

He's been on earlies this week. Oddly, I would have expected it to be a job for Martin.

Glenn · Sep 16, 2011, 17:35:38

The strange thing is, inside their office network the site loads fine using the same nameservers.

Rik · Sep 16, 2011, 17:37:48

That's weird, but I've known problems with the forum running like treacle and it's fine for them. I wonder if they connect differently to the network than us - though that really shouldn't affect DNS, of course.

Glenn · Sep 17, 2011, 17:40:33

Simon has cleared the nameserver cache, but I still can't reach the site, even after flushing my DNS cache, anyone else reach it from an IDNet DNS?

Rik · Sep 17, 2011, 17:42:04

No.

Simon · Sep 17, 2011, 17:43:39

Nope.

Niall · Sep 17, 2011, 18:58:24

Server not found using my iPhone via wifi on IDNet dns.

Niall · Sep 17, 2011, 18:59:41

Using 3G it loads fine (and fast).

Glenn · Sep 17, 2011, 19:05:05

Thanks for trying

Lance · Sep 17, 2011, 23:06:20

Could they be blocking Idnet ip addresses?

zappaDPJ · Sep 17, 2011, 23:29:12

That was my first thought Lance but it appears they can access it from IDNet towers

Glenn · Sep 18, 2011, 08:44:19

Simon seems to think it's a problem at the other end, but that doesn't explain why the connection is fast to resolve from other DNS servers?

QuoteThe Authoritative nameserver for this domain is flaky - it only occasionally gives a valid response. This problem is magnified because the the time-to-live for the domain is set to 300 seconds (5 mins), where the norm is 48 hours.

Simon_idnet · Sep 18, 2011, 09:02:49

The link I sent tests a bunch of DNS servers. Try it, then wait 6 minutes (for them to all time-out their caches (as instructed by the domain's time-to-live)) and then run it again in another window and compare.

cavillas · Sep 18, 2011, 09:59:03

Tried Idnet servers and was unable to reach the site but it is still ok on open dns servers. Maybe idnet servers don't like wars.

That wouldn't explain why Idnet users can access it using other DNS providers.

Lance · Sep 18, 2011, 14:02:59

True.

FWIW, I can get to it fine on my work laptop over VPN but can't get to it on my personal laptop over my idnet connection. Just tried both within seconds of each other.

.Griff. · Sep 18, 2011, 14:19:44

Testing from 50 locations worldwide and their respective DNS servers have no issues resolving the address.

Rik · Sep 19, 2011, 11:50:57

The site is now working, but seems to have a bad record somewhere as it drops out again periodically. If Brian refreshes the name servers, it works, but then disappears again after a while.

The IP address is 212.67.210.10, btw.

Glenn · Sep 19, 2011, 12:12:18

Thanks Rik, I reverted to OpenDNS to help with looking for my Grandfathers WW1 history.

Rik · Sep 19, 2011, 12:13:31

It's still resolving at this point, Glenn.

It looks a useful site.

Simon_idnet · Sep 19, 2011, 14:28:32

It looks like they have fixed the DNS problem today as this site has been resolving fine for me all day so far.

Rik · Sep 19, 2011, 16:48:38

Thanks for that, Simon. Brian kicked the nameservers when I spoke to him and, since then, the site has been behaving perfectly. It's amazing what a good talking to from Brian can do.

Simon_idnet · Sep 20, 2011, 10:33:45

I also kicked our nameservers (resolvers) several times over the weekend.

The problem is that the domain has a very short TTL and their DNS server quite often refuses to answer [probably overloaded as all the domains on the server have silly TTL values] - our resolver then caches that bad record.

The error that is being returned by dig is SERVFAIL which means that the domain does exist and the root name servers have information on this domain, but that the authoritative name servers are not answering queries for this domain.

Rik · Sep 20, 2011, 10:44:12

Thanks for the background, Simon.

Glenn · Sep 20, 2011, 10:55:16

Thanks Simon.

Niall · Sep 20, 2011, 15:37:50

Oo nerdy info. Me like
