yeah it’s not a great design. It could easily be a line graph where the the vertical axis is a log scale representation of each day’s uptime . You’d still be able to tell at a glance which services are stable (top marks across the board) and which services have dips. you could even still have the line change colors when it dips below a certain range if you just really wanted colors on it. it would even zoom infinitely since the horizontal axis can be arbitrary buckets of time, and the vertical axis is always 0%-100% uptime
