The server gw-44-137.pi9noz.ampr.org (44.137.0.1) mentioned on that page is also still available to AMPRnet users, but of course it is in Europe (Amsterdam) so not as accurate for users in the USA as a more local server would be. It has about 150 clients. The server itself is usually within 300us of UTC, it is referenced from 8 GPS clocks of different types (Datum 9390-52054, Trimble Thunderbolt, Meinberg) used in our same-frequency repeater network, plus various other external sources. It automatically fetches the leap-second announcement file from IERS once a month to handle leap seconds smoothly. Rob
