I have a huge packet loss (40%+) on specific destinations during afternoon times. Problem arises from 1-3pm every day and disappears at 8-9pm. Packet loss happens on routes through RETN LINX server, I've tested many other routes and no problems there, only with RETN route. I've opened CS ticket with the same question, but still got no answer. I'm attaching graphs from monitoring software so you can see where and when problem occurs. Would be nice to get some reply from tech stuff with suggestions how to fix/avoid this problem.

I've taken a look over your connection and can't see anything from our end and from our suppliers systems that would indicate a problem.
You mention that the issue only happens on RETN route, is that right? You don't have any other issues with different routes?

Yes, as I mentioned, problems only occur on RETN route (packet loss starts between ae2.ptw-cr01.plus.net and linx-224.retn.net routers as you can see on the graphs attached), for example, try to trace ya.ru server from your workplace. I believe it isn't problem with PlusNET itself or with "last mile" suppliers, the problem is with connection to the RETN LINX router. I'm not sure what could be done, maybe need to change routing tables to avoid RETN LINX server, or need to contact RETN itself and see what can they say.

As I see you have no packet loss, BUT you have different PlusNET router (ae1.ptw-cr01.plus.net) connected to the RETN network, my route is going through ae2.ptw-cr01.plus.net router. Maybe there is problem with PlusNET router (ae2.ptw-cr01.plus.net)?

Yes, I've been trying to get a different IP to see if I get different route (routes were different, but all of them had same issues with linx-224.retn.net router), that's why you see many reconnects.
As I mentioned in early posts, problem ONLY occurs within RETN network (RETN LINX), with all other routes (that I'm using) there is absolutely no problem.
