Update - As you have noticed by the number of messages about outages for thredds.met.no, we are still struggling with periods of overload.
From approx 12 CEST today we have introduced throttling on some of our most used datasets to reduce the load on our services.
Throttling means that the nnumber of requests per second must be below a threshold, otherwise you get a "429 Too many requests" error message in your download script. If you experience this, please try one or more of the following:
- Only sequential downloads, remove all parallell jobs. Wait until you get an answer befor you send the next request.
- Reduce the number of downloads by asking for larger downloads and do the extraction locally. Example: Instead of looping over the "four neighbour cells" when you want a grid extract, download all 4 gridd cells at once.

Monitoring - Over the past days we have experienced high and abusive loads on the public service thredds.met.no
This has resulted in a large number of "thredds.met.no - https down" messages on status.met.no.
We have been in contact with one organization so that the load is now reduced, but we will continue to monitor the situation and may have to block some of the users if this continues.
Please note that our priority users with an Service Level Agreement have not been affected by the outages.
Also note that in an unrelated incidence in our production system several models failed to produce results last night,and some forecasts are delayed. Our staff is working to restore normal production.
Thanks for your patience.

Network maintenance affecting data access on thredds.met.no ("storeB") Nov 11, 2026 10:00 - Nov 12, 2026 10:00 CET
A network maintenance is scheduled on Nov. 11. between 10:00 and 14:00 CET. This will cause many datasets on thredds.met.no to be unavailable during the maintenance and until the next day, Nov. 12. It mostly affects "Users", "Projects" and long timeseries in archives, while our weather/ocean forecasts shall remain online.
In particular the long dataseries under "Weather forecasts" ("MEPS Archive/", "AROME Arctic archive/", "MET post-processed products/ Archive + Long term consistent", etc.) will remain unavailable during the maintenance. A few long timeseries may be available in a shortened version (eg. only a week or month long).
