My resolver resolves buldoser.info -- SC's resolver doesn't.

There's a problem with the .info zone nameservice at this time.  See
below.

dnsstuff's resolver doesn't.  dnsstuff also has an ISP cache tool.
Quite a number of ISPs have the IP for buldoser, including my own, which
explains why I would be able to get the IP 58.20.176.18 and why a GET or
a browser function would work for me.

The dnsstuff story sez that when the root-server goes to the
ULTRADNS.info nameserver that it gets no response.  That is what is
currently broken.

So, the nameservice is flawed at the next to the highest levels.  If a
system can't get the IP, then the webserver can't be queried.  If your
provider's nameserver already has the IP, there's no need to get it at
the high levels.  There can be a webpage on a server, but if the user's
nameservice doesn't know the IP address, it isn't going to work.

If your ISP's nameserver has the IP, you can get the webpage.  But, if
it didn't, then the process would be to go to the root server which
tells it which nameserver to get the information.  If that nameserver
doesn't give the answer, the link is dead because of the nameservice
problem.

That name is supposed to have 4 nameservers.

  buldoser.info NS (Nameserver) managedns3.estboxes.com
  buldoser.info NS (Nameserver) managedns4.estboxes.com
  buldoser.info NS (Nameserver) managedns1.estboxes.com
  buldoser.info NS (Nameserver) managedns2.estboxes.com

You are supposed to be able to find out that information like this:

How I am searching:
  Searching for buldoser.info A record at b.root-servers.net
[192.228.79.201]: Got referral to TLD6.ULTRADNS.CO.UK. [took 95 ms]
  Searching for buldoser.info A record at TLD6.ULTRADNS.CO.UK.
[198.133.199.11]: Reports that no A records exist. [took 29 ms]

Answer:
No A records exist for buldoser.info. [Neg TTL=7200 seconds]

Details:
TLD6.ULTRADNS.CO.UK. (an authoritative nameserver for info.) says that
there are no A records for buldoser.info.
The E-mail address in charge of the info. zone is:
[email protected].
