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.
