Websites hosting major US climate reports taken down

>NOAA was caught using data from weather stations with faulty equipment and positioned next to new heat sources and only moved to correct the issue when confronted so I'd say this is entirely justified. The first step in any scientific process is clean data.

Assuming this uncited assertion is true, why would it be "entirely justified" to simply remove it without any particular reason as to why, nor discussion around the concern over data accuracy? Seems to me that the scientific community would be better served with an open dialogue rather than mute removal.

Yes, normally in a case where data were later shown to have been taken incorrectly, you would remove just the incorrect data but leave an unmodified copy of the old data available somewhere. Or, just leave a very prominent note about the change with a detailed explanation somewhere else. You would not take down everything because 1. That would deprive taxpayers of the correct data they had already paid for, and 2. That would mess up the data ingestion pipelines of the researchers who depended on the data.
