Download Test Files

These files are provided to help users test their download speeds from our servers. You can also run a speed test however downloading files can be easier to compare with real usage or where Java / Flash is unavailable.

Please be aware that downloading these files will count towards your download usage allowances imposed by your broadband provider and the large files may use up a large proportion of this if you only have a small allowance (1GB - 3GB for example). We suggest only testing the large files if you have a connection speed faster than 10 Mbps.

Instructions
Click the coloured label of the file you want to download to start the download process. If the download does not start you may have to right click on the size and select "Save Target As" (see here for an example).

These files will automatically use IPv6 if available, but you can select the IPv4 or IPv6 links to force it as required.
