May I suggest: https://status.postmarkapp.com
I'd send a PR myself but I'm literally getting up from my desk to prepare for travel. I've made myself a reminder for this for next week just in case it isn't added by someone else, but I figured there's value in the suggestion in the meantime.
Thanks, and again, this is very well done. I can imagine going to this whenever some app of ours starts getting problem reports.
May I suggest an array of squares (maybe something like dashing.io's demo) with color codes?
I would like to put it on a screen so we can just look at a glance (and remove certain squares we don't use)
I did a similar project a few months ago! One day after lunch people were starting to run around saying our system was down. I checked a few of our dependencies and realized it was out of our hands. (Still our problem, but nothing we could fix, only mitigate).
So Snu was born, take a look! Looks like we had a similar itch!
