Not sure its that simple. Here's my guess. Pure speculation. Sad that we have to speculate, but here goes:
1) Bandwidth management system is installed at launch.
2) WBS discover that "capped" users are still getting full speeds.
3) Disaster! WBS fears running out of bandwidth.
4) WBS throttles all use, particularly in office hours, while it finds out wtf is going on.
5) WBS can't fix it in promised time - buys another 15MB pipe from IS.
6) To preserve bandwidth, WBS continues to throttle at a level that makes it slow but usable, while they battle to find a solution.
And the reason why capped users are still getting full speeds: The bandwidth management software only limits single threads to 64kbps, not multithreads.
What makes me say this: I get 16KB/s max from the Telkom test. International single threaded downloads max out at about 8kB/s. Multithreads (10 threads) come down at about 40-45KB/s, but downloading multiple files simultaneously I can still max out at >120KB/s. And this pm, I loaded up Shareaza (haven't used it for several weeks), and those files with many sources were really flying. Again, I was frequently downloading above 100KB/s. So if anything, that is faster than I was experiencing pre-launch.
Anyway, that's my guess. Let's see what happens Monday...
