Your connection is most likely getting hung up at a network hub on its way to SE. Depending who it belongs to there is little SE can do same goes for their ISP and yours. Looking at the tracerts it looks like quite a few of NTT's hubs are suffering packet loss, Only thing SE can do is contact NTT and let them know and if I am not mistaken NTT handles SE's servers and ISP.
Sorry your having so much trouble connecting hope if clears up for you soon.
