Just putting these ISP servers in the pool would have this effect. We
maybe could add restriction for some servers so that they would only be
returned to queries coming from a particular subnet. I'm not sure if we
really want that. I would rather just add these servers to the pool and
let the distribution algorithm take care of it.
I have not investigated, but I would think that, rather like smtp relays
and dns forwarders,
many ISPs will have opened their timeservers only for their own clients.
There should be an access policy that describes which clients can
receive those specific
servers as answers on the query, or the clients may receive no response
or the ISP
may get angry about too many outside users. There may also be a
monitoring issue
because a centralized monitoring system may not be able to check those
servers.
Of course, when there is no such restriction, these servers can just be
put in the pool.
Maybe Ask can tell us if there are many servers like that in the pool,
and/or if an
effort has been made to have ISPs register their servers in the pool.
Until now, my impression has been that most servers are either personal
systems or
colo servers of opensource-minded companies. For example, the servers
of my ISP,
which otherwise is quite willing to make its services available for good
use, do not
appear to be in the pool.
