Why I can't get to XYZ web site?
This usually happens for one of two reasons. First, if the web site is running on a non standard port it may be blocked by security. Look at the URL/Address of the web site that you are trying to get to. Does it have colon and number in the address after the top level domain? Something like this:
If so this is what has happened.
In rare cases this can also be caused by a routing issue at our upstream Internet Service Provider (ISP). This usually happens with international sites or after our ISP has performed some type of network maintenance. In these cases it can be difficult to get the issue resolved because the problem lies with software or hardware not under the direct control of Computing Services.
In either case you should fill out a help request and list the exact URL you are having reaching.
