Contacts linked to Accounts Disappear

Contacts linked to Accounts Disappear

I had all of my Contacts assigned to Accounts.  Everyday for the last 4 days since the outage I come back to my account and the links are broken again, it appears to be on the same accounts too.

I have gone through each contact and made sure they were all assigned and linked to a valid Account.  But the link keeps breaking/disappearing.

Why does the link keep disappearing and what is being done to fix this issue????
