Description Neil Hauser 2012-02-14 15:02:26 UTC
http://www.w3.org/2001/xml.xsd takes > 1 minute to respond. My XML editor loads this for every XML file I edit, and during this time, it locks up until the connection times out. 

There appear to be other users having issue with this as well:

FWIW, It took me about 32 seconds a few minutes ago.  While this sounds important, I doubt that this is the right place to complain.  Sounds like a W3C system problem to me.

Thanks Dave. Do you know how I should classify this so that it gets to the right people?

Thanks,
Neil Hauser

This is not a bug.

All accesses to DTDs and Schema files on W3C servers are rate-throttled, because we get millions (sometimes tens or even hundreds of million) of downloads per day of these things. At times the bandwidth demand dwarfs slashdot :-)

Please use an XML Catalog to direct requests for the schema to a local copy.

I've marked it as closed "wontfix" - if we had a "closed cantfix" I'd use that instead; the throttling is a compromise so that we still serve the resources.

See http://www.w3.org/Help/Webmaster.html#slowdtd for slightly more information.

If this does not answer the question, please feel free to contact me directly, and I'll put you in touch with the systems team if appropriate.

Thanks!

Thanks Liam. Very helpful!

Don't see anything about XML Catalogs in my IDE's documentation, so I will see if our Web Proxy team can cache this content.
