That system metrics section is great. If more places which have status pages had that section, I would complain a lot less about their failure to update the status in a timely fashion. Case in point: the current status shows as green, but the system metrics tell you that something is indeed wrong right now since the request rate dropped sharply by ~90% at the same time that the error rate spiked from near zero to not zero (a y axis would be nice but it's understandable if the business doesn't want to disclose specific numbers, and the chart is still somewhat useful even without numbers).
The folks who make the AWS status pages could learn something from this.
