HE STATUS OF THE RELEASE OF THE NEW IMP SYSTEM (2600)

We have still not managed to get the new IMP system up.

To recapitulate:

We tried the first time May 15; but, completely under- estimating

the difficulty of distributing the new system to over twenty-five

sites, we never even got around to debugging the system.

We developed a suitable distribution mechanism and tried again

May 31. This time we got to debug the new IMP system and found a

number of problems which precluded leaving the new system up.

Trying again June 6, we got the new IMP system up and working

quite well, but the version of the TIP system which runs with the new

IMP system wouldn't work hardly at all. So we put the old systems

back up again.

The day before yesterday, June 20, we tried again. The IMPs and

TIPs loaded and seemed to fly quite well, so we left the new systems

up. But by yesterday, June 21, afternoon, with crashes happening in

TIPs at the rate of about one per hour, we backed off again and put

the old systems back up. (One TIP crash per hour in the network means

there is about one crash every eight or ten hours debugging with one

TIP which makes it nasty to debug.)

We plan to skip Tuesday, June 27, and Tuesday, July 4, and to try

again Thursday, July 6 (1972), and if necessary, again on Tuesday,

July 18, and following Tuesdays, as per RFC#343.
