I’m to the point I’m at -100 and they’re going to drop all 5 servers yet we’ve got dozens of users connecting from everywhere with no issues.

Where according to stats my server is not available and score drops. But not having any issues with wan connectivity, and no devices internally are having issues with the ntp server. I keep meaning to setup a box outside to sync to it and log to see if it loses any packets.. I too sent an email to ask, but haven't gotten anything back. I think its something with the monitoring or their network connection. What points me to something in their connectivity vs mine is that while they will show problems with the ipv4 server, the ipv6 which is just a he tunnel over the same ipv4 network shows no problems at the same time. If I had a problem with my server or my ipv4 the ipv6 should fail as well. On Tue, Jul 5, 2016 at 1:32 PM, George R.

Yes if I put up tcpdump on the Linux hosts and do a packet capture on port 123 I can see traffic from many other hosts coming into all 5 of the systems here and no one is reporting any outages (including where I'm employed that used them and monitors them - they were unreachable we'd have pages going off within 5-10 minutes). There is no firewalling that would block by IP or port for port 123 and nothing has changed here for set up at that time to cause them to suddenly drop out. Is there some way I can see what the Pool Status polling is looking like from the NTP Pool end to get more of a clue as to why this has suddenly started to fail? I've sent email to Ask but haven't yet received a reply.
