Hi, ISP shill here.

The SE admin literally tells everyone they can only provide support for user end devices and user end network settings (ie: your settings on devices you own and manage).

It is not incompetence, as much as you accuse them of. They cannot troubleshoot network problems they have no control over.

If you look through the posts from those you will see traceroutes. There's always one or two IP addresses with lag spikes. Those IP addresses are part of the network within the general network backbone. Those routers are owned by network carriers, not by SE.

I don't know how people imagine they are connecting to SE servers. It is not a straight connection from your CPE to their CPE. It is your CPE connecting to different routers along a path to eventually the last network router to SE's CPE. How your ISP has set up your routing dictates where to go from your CPE to SE's CPE.

The only way to solve this is to get the ISPs involved and have them fix the issue. You could always band-aid this by using a VPN and troubleshoot each VPN connection until you find one that circumvents that router.

Again, SE has no control over this. This is a ISP cause problem.
