May not be anything or may be..

I noticed a couple of days ago that some of our dns entries were mysteriously removed from level 3 servers which out of old habit are used for resolution (some of the ip's go back to uu-net/worldcom/mci)

Now the interesting bit is they were for private subnet ip's. They're working fine everywhere else.

Today the last of their dns servers removed the entries so I had users go to google (8.8.8.8) and all's well with our apps.

Level 3's entries for our external stuff is there, just the private subnet stuff is removed.

If others do this too and resolve with level 3....
