I'm an alumni from the CS Department at Wisconsin who uses OpenBSD and I recently got them to update their mirror page to reflect the fact that they mirror the OpenBSD releases. They have had a mirror for some time but I don't think they have openly publicized the fact. Their servers sit on fiber optic lines to the national backbone in Chicago and I have always found it to be one of the fastest OpenBSD mirrors available no matter my location (even in Europe). Sometimes they can be lax in updating their mirror to the current release but if you send a email to [EMAIL PROTECTED] (computer systems lab) they will generally update the mirror within a day (M-F 9:00-5:000). I was hoping that Wisconsin could be added to the list of download sites so that other people could take advantage of the services provided by such a outstanding institution.
roger btw the actual path to the openbsd releases for both http and ftp is mirror.cs.wisc.edu/pub/mirrors/OpenBSD
