I'm most likely just paranoid, but it's a bit annoying.
This morning I upgraded to the Flood plan for increased upload speeds and was delighted when my download speed also increased (From 187KB/s to 325KB/s). Now I had that speed for about 3 hours or so, until it was back at 187.6KB/s again.
Now I understand that for various reasons speed can be slower, however the line was at that speed and it NEVER has been before (It was great fun downloading a bunch of podcasts at 325KB/s!). The part I find most strange is that it's reduced back to exactly 187KB/s again. I don't know.. as I said, I guess I'm just being paranoid or something.
