Downdetector relies on user reports, so e.g. if a user's ISP is down and they can't get to Facebook, they might report Facebook being down (or vice versa). DD spikes are typically indicative of _something_, but it's not always the actual down service.

Gotcha. Although for a spike this large (over 1000) for a tech service (AWS vs Facebook) I'd give some credence to it. It could be that everyone who reported AWS as down is running on Heroku. Definitely possible. For comparison Azure [0] and Google Cloud [1] have spikes under 30.
