Re: Why aren't ISPs providing stratum 1 NTP service?
>So the list works... if you don't want to provide "public" services, adjust >the server to allow connections only from your own IP blocks. Currently I, and the company I work for, don't mind providing some services to the "public" Internet community. The company almost always gets more out of it than it costs to supply. I just don't want to get trapped into "supporting" public services. I get enough hate mail now when one of our no charge services goes out of service on occasion. A related, but more on topic for NANOG, issue is aligning more network services with network topology. I don't think putting a NTP stratum 1 server on the NAP network fabric is a good idea. I do think providers exchanging NTP across the NAP fabric is a good idea. Redundant voting catches a bunch of dumb errors. A packet saved, is a packet you don't have to carry. Its not as huge a problem as multiple MBONE tunnels transiting the same physical lines. But I'd rather have multiple associations at the edge of my network, and pass NTP in a structured manner around inside my network. The same thing is true for several other network services. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation - - - - - - - - - - - - - - - - -
