        • Performed the checks on 11 December.

          • Obsolete URLs that are still there:
            • RAL: https://xrootd.echo.stfc.ac.uk:1094/atlas:accounting/space-usage.json
            • LANCS: https://fal-pygrid-30.lancs.ac.uk/static/srr
          • RAL valid links obtained from its GOCDB page (https://goc.egi.eu/portal/index.php?Page_Type=Site&id=570).
            • Echo: https://s3.echo.stfc.ac.uk/srr/storagesummary.json
            • Antares: https://s3.echo.stfc.ac.uk/srr/ctastoragesummary.json
          • GLASGOW does not seem to have any SRR link on its GOCDB (https://goc.egi.eu/portal/index.php?Page_Type=Site&id=627)!
          • DURHAM is currently redirected to LANCS hence not much is expected.
          • Among the active ones are -- LANCS (another URL), RAL Echo, RAL Antares, LIV, MAN, RALPP, and QMUL.
          • Link to SRR documentation: https://twiki.cern.ch/twiki/pub/LCG/StorageSpaceAccounting/SRR.v6.pdf

        • The plan is to automate these checks.

        • Will be good to perform these checks once every week.
