To keep RSCS running on SEARN, we have a staff of one systems programmer and zero operators. The situation of HEARN is similar, except that they have operators. Both machines are EARN core nodes and handle a lot of traffic; neither has local users who could complain when they notice a problem. The monitored availability of the link between SEARN and HEARN, excluding march where we had a major hardware and software upgrade at SEARN, is between about 98% and 99.x% (the resolution of the monitor is not high enough to give fully valid results when the downtime is less than about 1%). This is our most reliable international link; others typically end up at a non-dedicated machine which is sometimes taken down for activities related to the support of local users. This is seldom a serious inconvenience, but does introduce a few percent of downtime. Eric
