    Website slow loading (possible DNS?)

    Hello all,

    I seem to be having a problem with slow loading. When I type in a couple of domain names on my browser, I noticed that it will take 2 seconds, before the site will start to load.

    On my status bar, it would show "Looking for www.domain.com" during that 2 seconds.

    It seems like the DNS is taking a long time to find my IP?

    a DNSstuff.com's tools report, shows my DNS as pretty healthy.

    What could be the possible reasons behind this?

    Try running a traceroute to it, and try getting to the site through it's IP directly. At least then you can rule out any possible problems with the network connecting you to the server.

    It is faster via ip.

    that 2 seconds could be use for DNS look up..

    it try to resolve domain.com to the server..

    for IP, it is directly pointing to the server which is why it is faster.

    If by chance you are using *nix as your desktop, I do recall Firefox DNS issue related to IPV6 on that platform; I don't know if it affected Windows but it likely did.

    Disable IPv6 in Firefox and see if that changes behaviour. In the address bar type:

    about:config

    And search for the preference network.dns.disableIPv6 and set that to true.

    This *may* help, if that is indeed the issue; with an older version of Firefox I found that I had to disable IPv6 at the OS level too.

  6. Is it still doing this? I had the same problem the last 3 days of last week and on Sunday night I logged in and checked that my zone files weren't corrupted. They seemed fine, but i added an A record for a sub-domain I had been meaning to add and incremented the zone files serial numbers. Within 2 hours everything was back to normal.

    It could have been a coincidence, but it may be worth a try incrementing your zone files serial number and let it transfer just in case there was something buggering DNS updates late last week.

    Its not perfectly clear whether the OP is talking about sites the OP controls, or web sites in general... i.e. is this a server issue which the OP has control over, or a browser issue.

    Reads like the latter.

  8. I just assumed that since he said he checked his DNS with DNSstuff.com he might be talking about his own sites, but yeah, it's a pretty vague question.

    Hello all,

    Thanks for the replies. Its sites that I have control over. I'm concerned because when I view other general internet sites, it takes < 1s for the browser to at least start to load.

    Whereas for my sites on my server, it takes at least 2 seconds holding on the "Looking for domain.com" before finally loading.
