There's a whole red bar when the website was down for 1 minute on a given day. I don't like it, and I wouldn't want to show that to my users.

I'd suggest you make the bar 1/3600 red, if the downtime was 1min - not exactly this, but you know what I mean.

Interesting. May be I can add a gradient from red -> yellow -> green with effected minute count, normalized to gradient threshold percentage. Let me try doing that

I think it's worth deciding what you want to communicate. If it's "we have good uptime, but we may lie", then it's a green bar always. If it's "we're honest about our downtime" then the colors should be distinct so users can notice and inspect the days that are <100%. A gradient runs the risk of looking "all green" even when some downtime minimal happened. If that's not the goal, then I'd recommend a step function (green, yellow, red, for example).

Dynamic? A 1 minute outage in the last 60 min seems more red-color-worthy than a 1 minute outage a few days ago.
