	When I worked at Belgacom Skynet, we made quite clear to our 
customers that we had time servers (actually, provided by the 
Belgacom Backbone service provider belbone.be), and we used these 
same time servers internally to sync the machines we operated.

	At that time, the only reason we didn't have our own Stratum 1 
time servers is that we had a short lease left on the building we 
were in, and even at the best of times we had a very, very hard time 
getting access to the roof.  After Skynet was consolidated back into 
the parent company, there was no sense -- Belgacom already provided 
their own Stratum 1 time servers.

	It must be a provider-specific issue.  Some tell their customers 
and actively encourage them to use the time servers, some don't.
