I find it quite amusing what they seem to consider "degraded performance" to mean -- I guess if you really squint, your service not working at all is actually just very large latency spikes (until the service recovers) and thus can be labelled as "services experiencing degraded performance for a small portion of our customers".

Even better "degraded performance" doesn't seem to count against their uptime stats. Issues is labeled as "degraded" with 100% uptime.
