Why is system so slow

i recvd email about system being corrupted?

Hi Jean, 

The slowness you experienced was an after effect of a major outage we experienced on Friday night when our database server crashed due to a corrupt hard drive. The site itself was not corrupted, the problem was with the equipment at our hosting provider SoftLayer and we’ve since restored everything from a backup. We should have any remaining issues sorted out by the end of today. Thanks very much for your patience.
