While you were updating your resume, has anyone here had a large number of contacts retired, resigned or just plain don't exist anymore?

I was applying for a job online. One of the first jobs I listed was working at Borders. The entire company has folded. Then I listed three schools where I worked. The principals were all replaced. Then I had to list where I student taught. The school no longer exists and the teacher who supervised me retired.

Out of all of my jobs, only ONE of my supervisors is still working at the job. Two of the buildings were I work were shut down and no longer even exist! I feel weird about putting in my resume and they are going to bump into tons of dead ends.

Has anyone else had a large chunk of their resume filled with names and places where there is no real current contact info anymore?
