I didn't change my keywords.
My daily budget is over the required for 100% delivery
I don't have any underperforming keywords...
Deliveries have droped to 10-20% for an entire day.
Does this just happen at times?
Is anyone aware of circumstances when this can happen?
THanks

The drop in traffic you describe sounds a lot like what can happen if your ads are no longer appearing on partner sites.
If you've edited your ads or URLs recently, this will pull them off of partner sites until they can be reviewed approved.
If this is not the case, then I'd suggest that you contact AdWords support. Since they can see your account, and those of on this Forum can not, you'll likely get a much more specific answer.
Best of luck, and have fun on WebmasterWorld! You'll learn an amazing amount here if you follow it every day. ;)
