As you may have already seen, Giganews recently announced support for 256 bit SSL encrypted Usenet access on port 443. The reason we decided to offer support for port 443 is that some customers were experiencing slow download speeds on port 563 due to port-based speed limiting on networks between their computer and Giganews.
One of the quickest ways to get around speed issues is to try switching ports. Many customers downloading on non-encrypted accounts have already found this out by switching their Usenet downloads from port 119 to port 80. This trick oftentimes quickly improves throughput rates when the source of the slowdown is port based-bandwidth limiting (networks limiting speeds on port 119).
There are two advantages to downloading Giganews' 256 bit SSL encrypted Usenet access over port 443. First, it will help you avoid port based speed limiting on port 563. Secondly, you may also avoid service-based speed limiting as your NNTP traffic is completely encrypted and running over a web-based port (port 443).
The goal of Giganews' support for port 443 is to offer our customers another path to access our encrypted Usenet service and to assist customers dealing with port based speed limits.
If you have experienced speed issues while downloading on port 563 and notice a speed improvement while downloading on port 443, please feel free to leave us a comment.
