and btw the bwmaster.pl is still rapidly restarting.

Thanks!

While not true in this case that you sent - static lists fall into disrepair frequently.  A couple of months back we tried this in the APAN region and found about 1/5 still worked well after being posted to an 'official' wiki.  

It doesn't hurt to ask those on the front lines that are adopting pS for some insider info - that request applies to all, even if they ate not in South Africa.

Thanks;

Hey Peter;

I would nuke the ESnet server too - NTP works best when the servers are within the same timezone/continent, it gives the algorithms a level playing field to choose from.

It's not really the case that a server outside of the timezone or continent matters.  The key is whether it's more likely than not that there will be asymmetry in the path to/from a given NTP server.  I don't really see much evidence of that with any of the servers in the list, except for possibly ntp.mtnbusiness....

A related note is that we are always looking to add new servers into our list around the world - if you know of 'open' clocks in the region that we can front-load into the list, that can be arranged.

Well, there's a published list of them here:
