My box started to hang 2-3 times a day - every day !! Only complete reboot (not even refresh) helps.
This means that problem is not with the provider (I have the fastest internet connection as this is my bread and butter), but rather with the box (memory cache issue) or servers.
It becomes worse and worse - looks like, soon it won't be possible to look anything without interruption. Wondering is company plans to do something about this problem.. Or ir will wait until frustrated clients will start to switch to service with another company
