Currently the uunet computer is a 14 CPU Sequent Balance 21000. (The Symmetry upgrade still hasn't arrived. It's currently scheduled to ship on 9/16.) It has about 1 gigabyte of disk space. Here's a "df". Note the filesystems that are mounted. It's a tad unusual... Filesystem kbytes used avail capacity Mounted on /dev/zd0a 7721 6143 805 88% / /dev/zd2d 7721 503 6445 7% /tmp /dev/zd0g 112197 98371 2606 97% /usr /dev/zd1g 500878 202540 248250 45% /usr/spool /dev/zd2f 216705 146926 48108 75% /usr/spool/ftp /dev/zd0h 104491 79315 14726 84% /usr/spool/news There is a 6250 bpi tape drive for backups and 24 megabytes of memory. There are currently 32 serial ports and an X.25 board. The X.25 board supports a 56 kbps Tymnet connection. The serial ports are currently divided into 10 800 number ports, 12 "local" direct dialup lines and 3 outbound WATS lines. There is a T-1 connection to SPRINT for the 800 service and the WATS lines. (All modems are Telebit Trailblazer Pluses) uunet is connected to the Internet via a local ethernet and then through the Center for Seismic Studies' arpanet IMP. It is connected to mcvax via a 9600 bps serial line running SLIP (surprise...). The mcvax line will be upgraded to 64 kbps as soon as they get it hooked up. (I.e. we ordered it and are now waiting for it). It is the nameserver and domain forwarder for about 100 domains. There are currently 421 uunet subscribers. Each day we average about 200 connect hours and transfer about 190 megabytes (this does NOT count Internet traffic). I think sendmail processes about 9-10,000 messages per day, but I haven't checked lately. We are feeding news to about 202 sites. Income is running about $50,000 per month. Expenses are running about $49,000 per month ($20,000 for Tymnet; $15,000 for Sprint; $5,000 for the computer). The average customer bill is about $125. The lowest is $35. The highest is often over $1,000. The size of the bill depends on how much data you transfer and how and when you do it. (E.g. using Tymnet during the day is 9-10 times more expensive that using Tymnet at night.) UUNET is run on a non-profit basis by the USENIX Association. I expect the connect hours and megabytes transferred to greatly increase Octoberish, when X11R3 is releasedish. Historically, traffic increases about 40% for the 3 weeks after an X11 release. (With a Trailblazer modem, you can uucp the X release for less money than MIT charges for the distribution tape; and you get it a whole lot faster [the same day its released if you are lucky]) If I could get MIT to put out X releases more frequently, we be doing really well!
