My application[1] with similar rpm as OP received 503 status last month for about an hour first time in 1.5 years, I assumed it to be an one-off issue at CF end. It happened while I was using it and so I'm now concerned if it's a regular affair for my users, most of whom are not from my geographical location(data-center). I'm a free plan user because my application is not monetized and obviously would switch to paid plan once it starts generating money. CF free plan has been indispensable for many such free projects. UptimeRobot(Free) doesn't show anything fishy, except for CF error 521 occasionally. Again UptimeRobot requires paid version to check for HTTP status message, guess I'll have to do it or setup a self hosted(recommendations?) solution to monitor HTTP status of CF Free application. If CF does perform rate limiting for such low rpm, I would prefer to be intimated as even third rate shared hosting providers do it and I hope CF wouldn't put their reputation on the line for something like this.
