I recently had a technician come round to my home address where I had a cable connection. The connection was really intermittent but he changed a part on the telegraph pole and fixed it. I did a speedtest.net test after that and found the speed had increased from 10Mbps to 15Mbps and thought that it was to do with the part. 

Turns out it wasn't, TelstraClear have just improved their speeds across the board. I received this today:

"On 1 October we upgraded your broadband plan to deliver more per month and faster.

We upgraded the downstream speeds of all our standard plans to 15Mbps and increased the usage allowance on most plans at the same time."

Not quiet sure what they mean in their table though:

Plan name, Old speed and usage, new speed and usage:

LightSpeed 20GB
10Mbps & 10GB
15Mbps & 20GB

Are they saying the old plan was only 10GB download and 10GB upload or something?
