Set up SNS notifications for critical alarms about open-api HOT 7 OPEN

@ojongerius I just set up UptimeRobot which has SMS notifications without the need for Twilio. It polls all our services once a minute and if any of them are down, it will email us and also it can send an SMS notification. It's easy to configure and I've already set it up for me and Stuart to get texts.

Here's our new status page: https://status.freecodecamp.org

What do you think of this service? Do you think it can be a replacement for PagerDuty, etc.? Will there still be significant benefit to configuring Cloudwatch and Twilio?

from open-api.

@QuincyLarson I can think of scenarios where your casual polling will succeed, but service is impaired for other type of requests.
Having said that I've caught many issues with simple scheduled end to end tests, that would have gone under the radar of specific monitors on metrics and unit tests.

I would not see it as a replacement, but a great addition 💯

@ojongerius Yes - I agree that there are plenty of corner cases that justify us having a more robust solution.

Just noticed that SNS has supported SMS via SNS since 2016 ..

@ojongerius Awesome - so it doesn't require Twilio integration? We could use it for messaging when we have outages?

from open-api.

That's right. Unless AWS is down... So there still is a strong use case for external monitoring that includes alerting.

from open-api.

@ojongerius Yes - but if AWS goes down there isn't a lot we can do anyway. It's gone down what - 4 or 5 times in 10 years?
