$ wget https://adp.eease.com
--2009-08-27 20:23:30--  https://adp.eease.com/
Resolving adp.eease.com... 209.168.243.5
Connecting to adp.eease.com|209.168.243.5|:443... failed: Connection refused.

The network team at that site is trying to figure out what the problem is.
Will update once they get back.
