some say its due to the maintenance on submarine cable or may be ptcl has deliberately did it anyway i search and found a fix which actually worked.
Step 1.
go to preferences > bittorrent > protocol encryption
set outgoing to :Forced
and check incoming legacy connections
Step 2.
Turn on hotspot shield (or some other vpn software)
it might take some time before you start getting good speed (and perhaps a couple of restarts to utorrent and hotspot shield)
I have tried this twice and it works
