- This is a wrong impression. There are many NTP servers in the UK. My
- department alone has about 100 or so. There are a handful of stratum 1
- servers, though most of them rely on the unsatisfactory MSF signal.
- BTW, the time zone that a server is in doesn't matter - NTP timestamps
- and radio signal sources like MSF use GMT/UTC. Round trip times to far
- away servers is another matter however.....
-
- I know of three radio clocks linked to stratum 1 NTP servers in the
- UK, though I have no explanation why these aren't in the clock.txt
- file on louie.udel.edu. These are:
-
- Server(s) Contact(s) Source
- bear.zoo.bt.co.uk John Sager GPS
- jcs@zoo.bt.co.uk
- beal.ncl.ac.uk Dick Snow MSF
- C.R.Snow@ncl.ac.uk
- Roger Broughton
- R.E.Broughton@ncl.ac.uk
- {ashby,albatross, Piete Brooks MSF
- gannet,swan}.cl.cam.ac.uk pb@cl.cam.ac.uk
- Martyn Johnson
- maj@cl.cam.ac.uk
-
- I understand that the servers at Cambridge are linked to one MSF
- receiver with multiple outputs. Please contact the people above for
- details of access policies before attempting to use their servers.
- Access to the GPS server is particularly difficult because it is
- tucked away behind British Telecom's Internet firewall.
-
- Anyone is welcome to peer with my Stratum 2 servers -
- ntp[0-4].cs.strath.ac.uk - these peer with a number of Stratum 1
- servers (and sources) throughout the world.
