It's true. We're finally on to BT's Superfast package! Finally our internet connection at home is fast enough to download a server backup each day without sacrificing the whole connection.
After doing a speed test this morning I have noticed that we've had a huge increase in speed. From 12Mbps all the way up to as high as 48Mbps, we're getting a much better all-round experience.
Upload isn't bad either - we're getting 8Mbps which is 16 times faster than the 0.5Mbps upload we got yesterday!
