It never ceases to amaze me that I can be 37,000 feet over the Atlantic in a tin box (writing this blog…) traveling at a speed of 594mph, with an outside temperature of -79F, and yet I can fire log events from my MacBook Air (excuse the pun) to Logentries and see them arrive instantaneously in my live tail view.
