If you're seeing significant differences in latency between instances, you'll need to run a trace against both good and bad instances and post the output here. See MTR and Connectivity Issue Primer for directions.

I am also having problems with latency on the Singapore gateway.

I have noticed that certain endpoints have a lower latency like 119.81.61.74

Example 1:

2023/12/25 20:30:39 25752578 ca3a69d2 [INFO Client 9528] Connecting to instance server at 119.81.61.74:6112
2023/12/25 20:30:39 25752609 ca3a5095 [DEBUG Client 9528] Connect time to instance server was 15ms

Example 2:

2023/12/26 16:36:34 11553000 ca3a69d2 [INFO Client 15740] Connecting to instance server at 216.12.203.93:6112
2023/12/26 16:36:34 11553031 ca3a5095 [DEBUG Client 15740] Connect time to instance server was 15ms

------------------------------------------------------------

While I was directed to endpoints within 203.27.106.0/24, the latency increases to 250ms as well:

Example 1:

2023/12/26 16:36:51 11570062 ca3a69d2 [INFO Client 15740] Connecting to instance server at 203.27.106.228:6112
2023/12/26 16:36:51 11570296 ca3a5095 [DEBUG Client 15740] Connect time to instance server was 234ms

Example 2:

2023/12/25 21:05:21 27834250 ca3a69d2 [INFO Client 9528] Connecting to instance server at 203.27.106.86:6112
2023/12/25 21:05:21 27834531 ca3a5095 [DEBUG Client 9528] Connect time to instance server was 234ms

Example 3:

2023/12/25 21:13:06 28299203 ca3a69d2 [INFO Client 9528] Connecting to instance server at 203.27.106.35:6112

Unfortunately, this is an issue with the new server hosts (GSL Networks - 203.27.106.0/24) GGG have started using. At the very end of last league these hosts appeared on the Japan and Singapore networks and they're terrible. They have the worst routing/peering I've ever seen anywhere.

I have no idea if these are just a temporary solution for league start or whether they're permanent.

Many thanks for your reply.

I suspected that these endpoints were the issue for me but good to confirm that.

I guess I will have to wait and see if things gets better later but hopefully GGG can communicate / solve that with GSL Networks
