Hi Jens,

The two servers for validator.w3.org have serious peaks of load.

We are planning to:

* monitor usage more closely, and deter abuse. Heavy users of the  
validator are strongly invited to install and use a local instance.  
Better and faster for everyone...

* add a third server. The server is being purchased with funds from  
the W3C Supporters Program. I encourage users of our tools to  
contribute to this program. Not only will it show that the Web  
community cares for the tools, it will also make it much easier for  
us to have budget for tools development and their infrastructure.

* ... and within a few weeks I hope to start beta-testing the next  
version of the markup validator. The development version shows some  
excellent performance improvements.

Breakage of these two features was unintentional. However, the irony  
of things is that I was about to put them at risk for the next  
version of the validator.

Both features are nice, but not directly compatible with the new  
parser we are using. That will be increasingly the case in the  
future, as we may use different parsers for different document types.  
They are also very marginally used - about 1% of requests to the  
validator make use of either outline or parse tree.

The outline feature is convered and much improved by tools such as  
the Semantic Data Extractor at http://www.w3.org/2002/08/extract- 
semantic


For these reasons, and mostly because my time is limited, I am not  
planning to work on these features, and they are thus at risk. The  
code is open though, patches welcome.
