htaccess Power

I've been using my .htaccess file to deny access to certain IP addresses and address ranges. Yesterday while adding a couple of entries, I mistakenly left a line consisting of only “Deny From”. I didn't catch it at the time but noticed later in the day that the entire domain was not responding. I assumed it was a problem at the hosting company (Pair Networks), so I contacted them later in the evening. Their technician responded quickly, pointing out the error in my .htaccess file and fixing it himself! Another gold star for Pair Networks whose support is excellent. And a reminder to myself to be more careful!
