Slow site speed

You may have noticed in the past few weeks/months that the site has been running very slowly at times. This is because another site that shares the same server as us has been hogging all of the resources, thus causing the other sites on the server to slow down. However, the host is in the process of moving the problem site to its own dedicated server so it stops slowing the other sites down, so in the near future this problem should be resolved.

I'm interested, if you are allowed to share, what site is this exacly?b

I don't know, the tech guy just mentioned another account, didn't go into specifics.
