It is not. Normal Impulse download speed for me is about 6.5 MegaBytes per second. That is for full game downloads, not patches. Impulse anywhere is always glacially slow, since it does not use local servers.
60 Kilobytes, being a hundred times slower, is therefore not normal if you have an internet connection that allows greater speeds. Possible explanations:
- There is something wrong with the particular server Impulse is using for you location.
- There is something wrong with your ISP.
- There is something wrong with the connection between your ISP and the particular server you are downloading from.
