All major service providers have something more or less like a status page (e.g. Apple, Google, Twitter, Facebook, and even small companies like Panic). There are many different options for implementing status pages (e.g., Atlassian, Better Stack, Status IO, Statuscast, etc).
Some of these options have the added benefit of providing alerts if customers choose to receive them, thereby reducing confusion and headaches. They also can provide the history of different services so it's easy to pinpoint if/when an issue may have been related to an outage.
