Here are the latest EARN statistics. Note that they measure real
availability, not the ratio of how often the BITNET link was up when the
Internet link also was. International lines suffer from many small
outages (from a few seconds to a few minutes), which in the case of
BITNET usually means the link goes down and stays down until automatic
retries bring it up, usually about 5 minutes later. Note also that the
SEARN figures are particularly bad due to major hardware and software
upgrades which kept the machine unavailable for a couple dozen hours. As
you will see, availability depends very much on the site. Egypt for
instance has awful results due to being shut down outside office hours
and during any religious holiday.
