(speak easy tests)

Test 1:

2003-11-14 04:30:45 EST: 1697 / 289
Your download speed : 1697625 bps, or 1697 kbps.
A 207.2 KB/sec transfer rate.
Your upload speed : 289603 bps, or 289 kbps.
Seems like broadband .. above the 1mbit barrier!

Test 2:

2003-11-14 04:32:36 EST: 1734 / 289
Your download speed : 1734722 bps, or 1734 kbps.
A 211.7 KB/sec transfer rate.
Your upload speed : 289247 bps, or 289 kbps.
Seems like broadband .. above the 1mbit barrier!

w00t! thanks mccoffee *pat on back* :p
