Is It Down?
Check a site from every Pingniner monitoring location at once. If it answers somewhere and not somewhere else, it is not just you — and that is the answer the single-server checkers cannot give you.
Knowing after the fact is the expensive part
You are here because something already looked broken. Pingniner checks from these same locations every minute and tells you the moment one of them stops answering, from whichever channel you already read.
