We monitor how much traffic we get from each country per day to check errors/blocking etc. (as I've previously mentioned).
Big drop-off recently from Angola & as usual it's an ISP (TV Cabo) changing their "is the internet working" config.
That prompted me to (again) look at how much we're serving to Fortigate "is the internet working" checks per month, roughly:
- 109 million web pages
- 10 Terabytes of egress
What a waste.
Make `head` requests rather than `get`, please!
