I wish it was only monthly. We have a Slack alert whenever there is reported downtime and it goes off at least once a week. Though granted it's seldom as business impacting as this current outage.
The problem CircleCI faces is that most hosted VCS now support CI/CD tools, as do most enterprise clouds. These will all have better integration with most peoples systems because they'll already be using the VCS or the public cloud (and if you're not using the public cloud you'd likely favor Jenkins / Concourse / etc over a cloud CI solution). So CircleCI's relevance is constantly being eaten at. The last thing they need it to damage their own reputation with these constant outages. I really hope CircleCI can turn around as it's great to see some competition but at this point in time I'm not feeling to optimistic about their long term future.
