maybe try doing a trace route to see how close you can get to connecting...
1. In Windows (not sure about other OSs) click Start and then Run... 2. Type in "cmd" without the quotes and click OK 3. In the new command line window, type "tracert petergay.t35.com" without the quotes and press enter
This will list all the routers your packets visited and probably where they stop. Copy what it gives you (right click inside the window and choose Mark, then highlight the text you want to copy, then right click on the highlighted area to copy) and paste it here.
Where are you located in the world? Some countries/ISPs block free hosting sites like t35. Do other t35.com sites work for you (e.g. http://chickenmeister.t35.com )?
I know the making-a-backup-process isn't all that complicated, but maybe it would be a good idea to have like a one-click button that explicitly says "create backup" on the control panel that would create a zip file to download.
Also maybe it would be a good idea to have like an email reminder service, where by t35 could send out emails on a regular basis (e.g. monthy) reminding people to create a back up. It should be opt-in, of course.
