(Which is rare.) short answer - iburst good, burst bad. I burst sends a burst when you first start and gets you synced up fast - setting it on one or two servers is reasonable and won't annoy anybody unless you restart a lot. burst sends a burst of traffic every time and is very annoying - it's really only useful if you're doing dialup and want to sync then disconnect. > > - Is support.ntp.org <http://support.ntp.org> consistently (very) slow > to load for everyone, or just me?

Both answers are ok - stratum three is not a bad neighborhood to live in and speaking as a stratum one operator I have no problems with people using my S1 server if they are in the pool (even the lowest bandwidth pool servers are handling 500+ clients). > > Thanks for the help!
