These files are provided to help users test their download speeds from our servers. You can also run a speed test however downloading files may be useful if you want to do so from different tools.
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.
Click 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". These files will automatically use IPv6 if available, but you can select the IPv4 or IPv6 links to force it as required.
NOTE: We provide these download files primarily for UK broadband users; although we do not prohibit their use by others, we do not allow scripted/automated download of these files. Our systems routinely block repetitive attempts which we believe are automated or abusive. If you get an 'unauthorised' error message, you can contact us (please include your IP address when contacting us).
