Why are our SharePoint sites are preventing user access sporatically?

Myself included, who is a farm admin, has run into this issue. I am able to edit list settings, entries, sites, etc. most of the time. Then from time to time I will be basically locked out and have no access to edit anything for a minute or two, then my access returns. Has anyone else experienced something similar? I am curious if the Web Page Security Validation has anything to do with the issue.
Thank you

This ended up being an external backup that was running hourly. It made everything read only while it ran.
