Latest status from an NWS employee:
Since an upgrade API isn't behaving optimally, the 503 errors are a known issue protecting the application. A fix for the application's database is expected no later than late this summer. We apologize for the inconvenience. This ticket will remain open until the issue is resolved. If anyone would like to be removed from the distribution list, please let us know via reply email. Otherwise, you will remain on the distribution list and updates will be provided when available, perhaps in several weeks.
