Singapore might be the least country in Asia in need of pool servers. Near 30 servers for 5 million popluation... After all, servers in Singapore can also help clients in Malaysia and Indonesia. > On May 29, 2016 1:36:30 PM CDT, Max Grobecker > <[email protected]> wrote: >>Hi Alica, >> >>I remember there was a discussion (regarding packet floods in Brazil) >>if pool servers >>from other regions/continents could be used in such undercommited pools >>like Taiwan or China. >> >>Is this already running?

Besides, if European servers are able to help, Middle East pools are better targets. They also lack servers (some countries with no server at all; querying these countries' pool will get no response!), and may have lower network latency from Europe. >From the network topology point of view, Asia continental pool should be further divided.

I would suggent a double-check on first drop mechanism: resend probing packet to no responding servers after serveral minutes. a. If the server is running fine, only overloading, it may be able to reply to probing packet after some time. We have double-check to confirm this, then go back to 20 mins checking cycle. No score modification (addition/deduction) is performed in this scenario. Further no-responding checks will still be double-checked. b. If the server is really down, no reply will be received either. The score can be deducted now, and go back to 20 mins checking cycle. Further no-responding checks will deduct scores directly without double-check. _______________________________________________ pool mailing list [email protected] http://lists.ntp.org/listinfo/pool
