    DNS Issues - Problems Viewing Webiste

    I recently moved hosting (about 72hrs ago to be precise). And am having trouble accessing my website, from my home network.

    OK so the nameservers have been changed for approx 72hrs now (I have given it this amount of time to make sure it's still not a propagation issue). The DNS settings have propagated around the globe as far as I am aware (using: whatsmydns.net).

    When I try to access my website from here I can very rarely get it, more often than not I get the error "Firefox cannot find the server at...." other times I get the old version of my site from my previous hosting, and then lastly sometimes I can access my site fine on the new hosting but it usually only lasts for about 10mins and then back to "Firefox cannot find the server.."

    Email also seems to be effected in the same manner (sometimes it comes through, other times I get a send/recieve error). FTP access is also the same however accessing it using the IP works fine.

    I have tried flushing my DNS on my computer, other computers on the network have exactly the same issues getting the site as I do. When I ping my website using command prompt it either can't find the server, connects to my old hosting IP or sometimes connects to my new hosting IP.

    Accessing the site via proxy works fine, so I assume this is a local issue with myself / my ISP. Using www.intodns.com it displays a couple or errors under NS:

    1) WARNING: Not all of your nameservers are in different subnets
    2) Different autonomous systems & WARNING: Single point of failure)

    My domain is: siteart.co.uk

    Is this a problem with my ISP? or is it even more local than that? Usually I have never experienced a nameserver change taking more than 24hrs.

    Any help would be greatly appreciated

    I can see your site perfectly.

    It is a local DNS issue, do you use an Internal DNS in your network? or do you use your ISPs DNS. If it is *internal*, we can do something about, if it is ISPs, you can't do anything but wait.

    Cheers for the reply soulhunter. No I don't use internal DNS, it will be my ISP's. I might send a report request to them and see if they can refresh them or something because this is getting really annoying.

    I've never known them take this long... Thanks again

    DNS propagation now a days don't take more than a 3-4 hours. The DNS report of your website is absolutely fine and this issue is something to do with your ISP.

    Did you tried accessing your website from other machines using the same ISP but not within your network? If the problem persists, it's your ISP else it's your local network that is in question.

    Hi madaboutlinux, Well my local network is simply a 1 wireless router, with 2 computers on it. Both computers on my home network have the same problems.

    I suppose I would need to find someone using the same ISP as me to find out if it's a local problem or ISP? I'm afraid I don't think I know of anyone using my provider. However I strongly suspect it is them. I'm going to contact them and see what they say (probably by phone, I don't fancy a 24hr wait for a eticket reply!)

    Yeah, give them a call... DNS may get propagated while you wait for 24 hours for a ticket reply.

    I suspect there is a real problem here - with the domain used for your nameservers. Technically this shouldn't be a problem because the ns1 and ns2 lookups are ok, but the main domain isn't. Perhaps the lookup failures are specific to your ISP's resolvers and / or triggered by the fact that you're hosting a .co.uk on .com nameservers (so the .uk nameservers don't have glue).

    That's a good guess but actually this problem do happen but when the domains are other way round i.e. when the domain is .com and the name servers are .co.uk.

    OK so my ISP's tech support were absolutely rubbish Firstly they had me on hold for 25mins, then I got through to someone who was unable to understand my problem so surprise surprise I was put in another queue for another 15mins!! Somebody answered... I started to explain my problem again, then suddenly I was back on hold with no explanation! I guess whoever it was couldn't be bothered to deal with it, so just stuck me back on hold. I braved the cheesy music for a further 10mins before giving up and hanging up. All in all a pretty unproductive 50mins of my day.

    So I just settled for a eTicket thingy. No reply as of yet, and I'm still experiencing the same problems this morning... GRRR

    Unfortunately I've tried flushing many times with no luck, Thanks anyway.

    Yeah I noticed that intoDNS was showing a few errors for that domain too. I think there is quite a few websites hosted under those nameservers without a problem though, and most likely a lot of them will be .co.uk's like mine.

    Many thanks for the replies guys. It's always good to find a helpful forum, hopefully I'll get to the bottom of this problem sooner rather than later

    Does anyone know I can use different DNS settings for my broadband connection, i.e use another ISP's rather than mine?

    Quick Update

    Changed the nameservers in my router from my ISP ones to some from http://www.opendns.com/ all seems to be working perfectly fine now

    Why I didn't try this earlier I don't know, it literally took 2mins and the problem is sorted. I just hope that the problems I was experiencing aren't affecting anyone else trying to view my site.

    Unfortunately you can be fairly sure that any visitors coming to your site from your ISP will have the same problem, and perhaps visitors from other ISPs who run the same software for their resolvers. A better solution would be to use a specialist dns service, eg. zoneedit or dnsmadeeasy, for your site. Another consideration: the consecutive IPs suggest that your host is using only one nameserver - a very common setup but not ideal. If this is the case even a free dns service would probably be more reliable.
