• Noirlab raises this exception The astroquery.noirlab module module is expecting an older version of the https://astroarchive.noao.edu API services the API is of version 5.0 but the module checks for version 2.0 as the latest version. Would open an issue to correct that.
• The svo server http://svo2.cab.inta-csic.es/ times out
