I have a web server thats hosting a couple of websites on it.

On my home network and on my 3G iPhone the websites load really quickly, even after the cache has been cleared.

But when I get to University (and some of my users have been experiencing this problem) - the webserver is unreachable, often times out, slow to respond - and (if lucky) when it does send the initial HTTP headers it can take up to 30-60s to send the webpage's data.

While I'm at university, however, I can access cPanel (Port :2082), WHM and SSH. Although these services are often very very slow, and sometimes unreachable.

It's hard to fix this problem because the site works fine at home.

The server load/memory hovers around 1.2/15% respectively on average. Which I believe is pretty average.

Have you ever experienced such an issue? Thanks.

Answering Comments:

I can Ping the Webserver with Similar MilliSecond Response to my home network.

When i TraceRoute, I get to my Universities Gateway and then from there the hops time out until HOP 15-20 (but this is consistent with other websites such as google).

The Webserver is located in a Datacenter in the US - 2GB Ram, 2.5Ghz Processor.

DNS has been set up properly, Ping/TraceRoute can resolve the IP quickly.>

Although The internet connection is slow here, no other website (that I access) seems to have much of a problem.


First try:

  1. What is the pingtime from the university to your home network? If it's long then it may be network problem rather than server configuration problem
  2. Does connection from other places work? e.g. internet cafe? If so - then it is even more likely that the connection from university had a problem.
  3. Where is the webserver you mentioned? Is it in a data center or at your home? Has DNS service been setup properly?

Give us some more information to answer with =)


I found the problem.

The firewall was blocking 99% of all inbound connections.

I had to turn off SYSFLOOD on the cPanel firewall and it fixed it.

Thanks for the responses.
