Re: [cobalt-developers] Weird DNS / Subdomain Issue

[Matthew Nuzum <cobalt@xxxxxxxxxxxxx>]

Jeff, one of the most useful troubleshooting steps that can be done is
to look in your logfiles.

You'll want to see what a successful request looks like, and what an
unsuccessful request looks like.  Comparing the two will probably point
you directly at the problem, but if it doesn't, post it here so that we
can have a little more details.

P.S. are there any other funny things happening around the same time?  
Does it always happen at the same time of day?

    I am setting up a DNS system that allows subdomains to be created
    automatically when a new user is created.  These subdomains then point to a
    ColdFusion script that I have written that automatically redirects the user
    to their correct folder to display their website.  I am doing all of this
    with a seperate MySQL database table and have just entered a wildcard into
    our DNS tables to handle our domain name so that all traffic comes through
    to our domain name no matter what is before it.  Then, I use the ColdFusion
    script to parse the subdomain and pass the user along.  It all worked fine
    for a couple weeks, however, now I am having some trouble and I am hoping
    someone can help me figure this out.
    
    Sometimes I go to subdomain1.myhost.com and it works beautifully, correctly
    redirecting the user to their correct folder via the ColdFusion script.
    Then, other times I go to the same subdomain1.myhost.com address and I get
    the good ol "The Page Cannot be displayed" error.  I can't figure out why I
    can go to the address for a couple hours, and then a few hours later that
    address is not reachable.  Then, after a few hours of not being able to
    reach the address, I go back to the subdomain1.myhost.com address and it
    works!  At least for a few more hours before it goes down again.  This has
    been going on and on for a week now.  Is it possible that I have a virus or
    a trojan horse or something?  I can't figure it out.  We host our own
    primary and secondary DNS servers on seperate machines.  They both look
    identical to each other.
    
    Has anyone ever experienced subdomains or even domain names that have worked
    for a few hours and then stopped working for a few hours and then started
    working again a few hours after that?  All of this weirdness is occuring
    with no changes to the Cobalt server at all.
    
    If anyone can help me in any way, I would be most appreciative.
    
    Thank you,
