Over the last 2 years, we've had ~4 major outages on their platform. The last of these was so severe we're moving everything back off and over to aws.
If we set the bar at events that break customers who have taken reasonable steps to be geographically distributed, 4 over two years is horrible. Things here are cascading router failure, BGP misconfiguration or external hijack, major peering dispute, bad push to critical systems. If these aren't rare, it's likely to be avoidable failures caused by the provider. Sometimes the earlier types of problems hit here too --- fiber cuts between regional data centers can be major problems if more things run on that fiber than expected; it's always fun to learn redundant fiber is in the same bundle, and usually that's learned when the bundle is cut.
