Connecting to these resources temporarily adds your machine to those already being served by the host's computer system. Host institutions, especially colleges and universities, need to serve their own constituencies first. Conduct your visit so as to reduce demands on the host's system. Remain on the system only long enough to get your information, then exit off the system. Download files early in the morning or late at night according to the time zone of the host computer.
Some hosts post time restrictions for connecting to archive sites.
Adhere to those restrictions, and remember to think in term of the current time at the host site, not of local time. It is the user's responsibility when downloading material to check for copyright or licensing agreements. If there is any doubt, don't copy it. Support for downloaded programs should be requested from the program's originator, not from the host site.
