RE: Our server keeps getting blocked

I have had the same problem with China Telecom (in Guangdong area =
though)
and complained very hard to them. They could not explain the source of =
the
problem (we changed host and the next day the new host was blocked), =
even
installed a PC in our DMZ to check the connection (it once lasted for =
4-5
days... hard to handle business that way) and for now the problem is =
gone..
until it comes back.

So you're not alone.

Subject: [blug-tech] Our server keeps getting blocked


Hi All,

I am hoping one of you might be able to provide some insight into a =
problem
we are having with our server.  Our company uses a server which is =
hosted by
lunarpages.com in the US.  Over the last several weeks we have been =
having
an unending stream of connection problems.  Access to our website and =
mail
server keeps coming up and going down (although it stays down more than =
it
is up). =20

I have been doing some research into the issue and this is what I have
discovered:
1.  	The server name is resolving correctly so I don't believe it is a
DNS issue.
2. 	If I go to our site via a proxy server located in a country other
than China there is no problem.
3. 	If I go through an anonymous proxy within China I cannot get to the
server.
4.	The problem is intermittent (sometimes there is no problem, then all
of a sudden we cannot connect, then it will eventually work again)

Additional info:
This problem was getting so severe that we recently changed hosts (now =
we
are using lunarpages.com).  After the change the problem seemed to have =
been
solved (with only the occasional connection problem), however, now it
appears that the same problem is occurring.

I would love to hear any ideas as to what the issue may be.  If the host =
was
being blocked, why would it only work part of the time?  Perhaps it is a
problem with our office server, which functions as a router (IP
masquerading).  However, in the past it has been working perfectly and =
the
configuration has not been altered anytime recently.  Furthermore I can =
get
to any other website just not ours. Frustration extreme!!!!!

Thanks in advance,

Ben
