We've introduced Instant Alerts, an optional service that notifies you when there is a problem with your site. You can specify the email addresses and/or mobile numbers that should receive the alerts.
At the moment you can receive alerts when your origin server:
- Times out
- Cannot be reached at all
- Returns an error
To avoid repeated messages, each alert has a cooldown limit you can set from 30 minutes to 24 hours.
If you're using a service like Pingdom to check that your site is up, you probably will want to enable Instant Alerts. Services like Pingdom might be served pages from our cache while your origin server is actually down.
