junghao commented 1 year ago

Downstream services failed due to sending the following query which created unexpected result:

https://service.geonet.org.nz/fdsnws/station/1/query?level=channel&format=text&network=NZ&endafter=2033-03-19&startbefore=2023-03-19

A rollback as emergency fix has applied.

Most of active sites having endDate of 9999-01-01, and the query is generated by geonet-api which use "a year later" as default of backend query.
