HP is scanning my vulnerabilities, is this OK?

view full story

http://serverfault.com – I have free server at HP cloud, and I am receiving scans from them like this. It is from and reverses to internal-scanner.ops.uswest.hpcloud.net. I have been told numerous times that this kind of scanning is not right, so I cant do this myself in my network. Is this really OK? Basically scanning services running on my own server as well desktops.
