Although it can be useful at certain occasions, using a speed test to determine how fast transfers should be isn't the best idea. A speed test doesn't take everything that can affect our service into account, like firewalls, antivirus software and other things that could possibly limit or even block your connection to our service.
A specific example: if your network or internet service provider is limiting traffic to and from Amazon Web Services, a speed test won't pick up on that. However, it will definitely have an impact on how fast your transfers to and from our servers will be, because we use AWS for all transfers.
The same thing goes for things like firewalls, proxies and antivirus software; they could be blocking our domains, but a speed test won't know or show you that.
Something a speed test is excellent for, is showing you what your current speeds are to the speed test's specific server. If you'd like to investigate the connection from your computer to ours, we would recommend doing a traceroute to our servers instead. For more info on that we would really appreciate it if you can contact us via "Submit a request". Since the details on doing a traceroute are a little more technical, we want to offer some personal assistance with it.
