We're an IT company up in Newcastle, but far enough out in the sticks that internet access is an issue. We used to enjoy 5Mpbs connections through Demon, then moved to a bonded system through a local ISP called Wildcard which gave us 7Mbps.

Then a numpty crashed into the BT cabinet at the end of the street, and our speeds died along with it. The Maximum we could get was 3Mbps and the bonded line kept dropping.

We discussed EFM as an option, but decided to switch to a 4 line 21CN system from AAISP, expecting 4x 3Mb so about 12Mbps. I thought in for a penny in for a pound, so ordered 4 brand spanking new phone lines too!

That bit was worth every penny.. While the Engineer was installing them I took my little ADSL2 tester up and found 1 line syncing at 6Mpbs, but the others down at 3Mpbs so I asked the engineer to investigate.

Turns out there's more than 1 cable between the cabinet & the exchange, and the cable all my other lines on had been joined.

The BT engineer politely moved all 4 lines onto the faster cable - so I owe him big thanks!

Anyway - after the lines have settled I now get 24Mbps!

The only problem is I can now see us chewing through our bandwidth allowance quicker :(

Now, had the original ISP been a bit more proactive with the speed issue we would probably have stayed - but despite having multiple BT engineers telling us the line was fine we knew we'd had better performance before.

In summary : AAISP - fast connection, good communication, not cheap but value for money.
