More about MetAlerts + removal of Verticalprofile

As promised, here are some more details about the new version 2.0 of MetAlerts, which will be officially launched on 7 May 2024. At the same time we will be deprecating version 1.1, which is planned EOL on 2 Sept.

As mentioned the new version is using a new CAP profile (v2), which means more data in the GeojSON feed. Since all previous CAP and GeoJSON alerts in the archive are using profile v1, these are not so good for development and testing until the archive is populated with v2 profiles some time next year.

To compensate, we have added an /example endpoint which works just like the others, except that the alerts will remain in effect for the next 10 years. Currently the event types forestFire, blowingSnow, rainFlood, lightning and rainFlood are supported, more will be added later.

We must also stress the importance of handling redirects correctly! This is mandatory for the whole API, but we will shortly (starting next week) be serving most CAP files with a redirect to our object store, so make sure your systems are compatible before 7 May.

Moving on, the Verticalprofile product will be terminated on 31 May 2024. This is mainly being used by our Halo site (for the public service sector), but as this is being replaced by Værio it is no longer needed. If you are a current user, please contact us and describe your requirements for an eventual replacement.

Finally, we would like to apologize for the intermittent service disruptions on 10 April between 14 and 16 UTC, which was caused by a malfunctioning spine switch causing one of the filservers to be unresponsive. We're not sure if this was noticable for external users, but the graphs show some dropouts.
