mrbluesky: I was having issue uploading my stream to my stream hosts overseas. Massive latency issues between my router and the internet gateway, was causing my stream to buffer so badly that I was losing listeners. When testing to the same remote IP address from another provider there was no latency.
Two separate calls to the "Manila Telecom Call Centre" didn't do anything but raise my blood pressure. They kept insisting that they could find no problems and wouldn't escalate me to 2nd or 3rd level support.
I filed a formal complaint with Telecom management about the appalling customer service of their Manila help desk and after a 2 weeks investigation...I have not again had the issue for almost 2 months.
Will the wonders of the monopoly ever cease? Probably not.
Have you tried logging a case again with traceroutes and examples of when the traffic is slow, then if you don't get any joy tried contacting Telecom via twitter @telecomnz ??
99% of the issues are caused by poor home wiring. When you tested the same remote IP with another provider was that at someone elses house, or did you use a different username/password to login in your router? Since I seem to remember that if you are with Telecom you can't use another providers username and password and see if they work.
I would highly recommend doing an isolation test and making sure your line is clean.
