We have observed the same problem for all stations that we monitor in our software systems.

The issue started just before midnight on the 11th. Since then we find that

• Querying data from times after 2020-02-11 00:00:00 result in a 404 error
• Querying data from times before 2020-02-11 00:00:00 will return results
• Querying data that crosses this boundary will sometimes work (as long as it includes time before 2020-02-11 00:00:00), but it is inconsistent

Note that queries built using the URL builder (http://service.iris.edu/irisws/timeseries/docs/1/builder/) exhibit this problem, so it's not a user issue.
