below is my point of view of this slow speed chaos :

Jaring, AIMS, Tmnet, NTT all of this datacenter here at malaysia using TM backbone to get connected to oversea..

the main core problem here is with the interconnection here at TM line to outside world.

I am Ex-TM LSS( Leasedline and Switch Services) Team (2002-2006).
Managing Leasedline from 256k up to STM64 node that interconnect the whole Malaysia including sabah and sarawak.

Usually TM network are using RING topo where you can still have backup line for reroute purpose.
I am assuming the main route to connect with other datacenter at US/UK or Jap has been failure so the are now using the other route which is the longer way..
That makes the browsing to other website that using outside server taking very slow as it use longer route plus every one now using that one line making the route even jammed!
It might not a problem in our part (malaysian) but rather external part like underwater cabling ect..

I just hope that TM LSS and PCN international team will resolve this issue as fast as possible.

no use to try your luck today..
just go to bed and wish that tomorrow will be a better day for that tmnut sucking ppl money for bb..huh!
