If you have consistent connection trouble, the best thing to do is run a traceroute when it is happening and look for unusually high pings and packet loss along the way. Sometime multiple traces are needed to find the hop with the trouble. If it is on your home network or within your ISP's wide area network, you should call tech support and a good agent will know how to address the trouble. If the bad hop is further down the internet backbone, maybe your ISP can contact the responsible party. If the bad hop is on SE's end or is with their ISP, then contact SE support. Sometimes it takes more than one support request to the responsible party to get the connection fixed because unfortunately not all agents are as knowledgeable as others. For awhile people were posting traceroutes on here showing a bad hop in New York with SE's ISP. I don't know if that was fixed but it was discovered weeks ago so I hope it was.
