If you had 100,000 visitors to your web page you would have 1 gigabyte of traffic. We determine storage usage by a daily average of the combined total size of an account's home directory, anonymous FTP directory, and mail file. We determine FTP traffic usage from the FTP xferlog file generated by the FTP daemon. You can use additional space as you need it. We will charge you based upon your average space consumed throughout the month.
Traffic is separate from storage.
If you use additional storage it does not change your traffic total or increase the amount of traffic included free. So the answer is no, you don't get extra free traffic because you have a giant web site. You can use telnet as necessary to configure your account, but as this is not included in your traffic for the month we can't allow you to conduct a large number of simultaneous telnet sessions without prior arrangement to pay for the additional bandwidth consumed. If you do, it will force them to have to discontinue business with you because they will be losing money. The only other alternative to them dropping you is if they cheat you by throttling your server down so that it doesn't use the full T1.
