Hi guys I’m running 3 NTP servers, two of which were added two weeks ago in the India zone. The third one was added two days ago. Here are a few things that I noticed: The two servers (let’s say A and B) I added earlier show a sawtooth pattern in the monitoring graph. [image] The third server (…

It happens to many IPv4 servers. @Ask is working on a new monitor-system to minimise this from happening. Nothing you can do or change to make it better. It’s just UPD-timeouts that happen underway and as the routing of IPv6 is faster is happens far less. Therefor a new system is in the making t…

I’m working with Rishabh to collect traceroute, etc. This situation differs from the many others we’ve seen, as it affects IPv6.

Hi guys I have more new findings. I asked the team to move the zone of server C from above to India, Asia. Remember, server C was working flawlessly, perfect 20 scores, without any dip whatsoever. As soon as the zone was changed to India, I saw a slight dip within a few hours, followed by the res…

this maybe caused by unstable connection from oracle india to ntp pool san jose(i.e you know that some routes is more congested while some are not), so even you have stable connection towards all other destinations, if your server connection with ntp pool san jose is unstable, the score will defini…

I have 3 servers running at Linode in Mumbai, which are also prone to some flakeyness. This affects both IPv4 and IPv6 - i.e. pool.ntp.org: Statistics for 2400:8904::f03c:92ff:fe80:f6ac Also routing from there to my home internet connection (Deutsche Telekom, AS3320) is about 5% lossy. If you need…

@fxxkputin I was running another NTP server from my home, which too had the same problem. Not only Oracle, but also ISP Jio and Airtel have the same problems. Btw, can you share the address of the San Jose monitoring station? I’ll share the ping results from all the systems I ever ran NTP server. T…

Okay, so for the people on Oracle cloud who are having this issue, this is caused due to the conntrack table on the VNIC filling up and dropping the packets, you can identify this by looking at the metrics here: Compute > Instances > Instance Details > Attached VNICs > VNIC Details To overcome this…

this is my new ntp server and have been run for more than 1 day and score only increases, so it shows that the monitoring station and indian zone have no problem
