NOBU incredibly slow

My Norton Online Backup is incredibly slow.

 

I had to reinstall it and have, so far, been unable to do an initial back up.

 

My connection is 'upto 60Mb' and I get just under 3Mb upload (see: http://www.speedtest.bbmax.co.uk/results.php?t=1400355058&v=22324979).

 

I also have been having trouble getting on to the NOBU website occasionally.

 

Is there maintenence being performed, or something else, that is causing this problem?

 

Is it an issue my end?

 

Is anyone else having this problem?
