Sounds like a clogged vent--birds, squirrels???

Had a really curious situation that I've never encountered before. This
morning for about five minutes all of my sinks and toilets started
violently
'gluging' and 'burping'. The water in the toilet pans started splashing
around, bubbling a and emptied. It sounded a bit like whole-house
indigestion! Any ideas what it was and how to prevent it?

Cheers
