Apologies for the inconvenience.
There was a small problem with our main high speed download link last night and we had to switch to a back up.
We hope to have the main link back up soon, but unfortunately that doesn't help you now.
I just tested the link myself and I got an initial download speed of 470kB/s but after pausing and resuming the download it dropped to 60kB/s. I just started a new download and now I am getting over 1,200kB/s. So, as you can see it is a bit variable and will change based on multiple factors such as the number of concurrent downloads.
As others have suggested, third-party download manager software might speed this up.
Sorry I couldn't be any more help. Another staff member who deals more directly with our downloads might be able to advise more when the come online later today.
