You can read the first 9 ways here: 9 Ways ISPs Screw You Over.

10.  ISPs advertise speeds in a way that only people who have an understanding of how data is stored can translate.  For example, lets say you pay for a “10 meg” connection, thats not actually 10 Megabytes per second you’re capable of, its actually 10 Megabits.  Now, there’s quite the difference between Megabits and Megabits, but not so much a difference in the acronyms.  MBps is for Megabytes and Mbps is for Megabits.  The real issue here is if you pay for a 10 Megabit per second connection, your maximum transfer rate is only going to be 1.25 Megabytes per second (there are 8 bits in a byte).  Thats also theoretical, you can very rarely actually achieve the theoretical bandwidth provided by your ISP, unless you’re trying to load their homepage or hit a url that they detect doesn’t exist and throw you a page full of ads.

I’ve been a long supporter of transparency from ISPs, but we’re likely never to see that up here in Canada – at least not until the CRTC cracks down and decides we, the consumers, need some competition and not more monopolies.
