The IsUpMap lets you check the status of over 100 major sites at once

This app looks to be incorrectly parsing Slack and Auth0 official status page and showing incidents as ongoing that are not

And those are just the 2 that I checked.

To be fair, accurately scraping and normalizing data from status pages is really hard to to do consistently (my company has a team of 5 engineers to do it and it's a lot of work).

Services like Cloudflare and Twilio have so many POPs globally that one or more always have an outage going on. Then there's the question of whether it's a major outage or a minor outage. Even though major status page providers like Atlassian and Incident.io have public status APIs (Cloudflare uses Atlassian), it takes more than just parsing them to determine what is "down" and at what granularity.

I run an outage detection service - and some of these issues, like parsing hundreds of - sometimes undocumented - status APIs, make for an interesting engineering problem.

Ouch, Azure isn't even present

Where does this draw data from? It's a similar visual concept to what we're doing at ThousandEyes within Internet Insights (see https://www.thousandeyes.com/outages/) however we make it fairly clear how we are making these determinations. Our data comes from billions of daily pseudonymous metrics from within synthetic tests running across thousands of agents around the world.

If you're drawing the data from a public resource like downdetector or using the sites status pages, then you may not be reflecting reality, but it should be clear what the provenance of the data is.
