We ran from + 10:00am on that day until Wednesday afternoon with very few network + problems attributable to the new system. We are quite pleased with + this performance, and expect to leave the new system up permanently!! + + We are, of course, aware that in any system of this size, bugs may + crop up at any time, and we solicit the help of the network community + in finding them. We also believe that the new system may have a + different "feel" to users, both terminal users and Hosts. We urge + everyone to have a bit of patience while getting used to any change in + the "feel" of the network. On the other hand, PLEASE REPORT ANY + SUSPECTED NETWORK MALFUNCTION TO THE NCC AS SOON AS POSSIBLE. + Evidence of bugs, guesses as to what went wrong, etc., are always + useful in hunting bugs, but don't let the lack of positive proof delay + the reporting of suspected system malfunction. The NCC telephone + number is (617) 661-0100. Feel free to call collect! + + The one known shortcoming of the new software is the exacerbation of a + long-standing TIP software problem. The TIP now often appears to + neglect sending an Allocate control message for some active + connection, with the effect that the Server-to-User path becomes + blocked. We are giving the solution of this problem the highest + priority! (Our current data seems to indicate that this problem is + most likely to occur when there are several users and when the Server + Host is a TENEX system. If you know of other situations where this + problem has occurred, please let us know!) + + Now that the new system is up, all sites with Model 516 IMPs will be + contacted by telephone and asked to reset the switches on their IMPs + as follows: + + HALT INH - on + W.D.T. - on + AUTO RSTRT - on + MEMORY PRTCT - on + + + + + + + [Page 1] + +SITE POWER PROBLEMS + The network has recently been experiencing serious difficulties + related to the annual problem of more demand for electricity than is + available during the summer months. For example: + + During the month of June, between 1/4 and 1/2 of the + IMP down time was due to site power failure. + + During the weekend of July 15-16, two sites were down + all weekend due to air-conditioning failure which was + apparently related to power failures or brownouts. + This left several sites connected to the rest of the + net through only one path which, according to Murphy's + law, eventually failed - leaving nine sites partitioned + from the remainder. + + On July 18, an underground power transformer supplying + power to the entire computer room at site 27 failed, + putting IMP 27 out of action for several hours (anddit + could easily have been several weeks.) + + Obviously in these cases there is little that either the NCC or the + site can do to restore service. We expect these situations to + continue or even get worse as the summer continues. Please try to + restrain your annoyance when these situations arise; we don't like + them either! + + + + + [ This RFC was put into machine readable form for entry ] + [ into the online RFC archives by BBN Corp. under the ] + [ direction of Alex McKenzie. 1/97 ] + + + + + + + + + + + + + + + + + + + [Page 2] + -- cgit v1.2.3
