Greetings,

Whereas as Roland's recent figures are based on aggregating DSA availability
information, and are a measure of DSA availability, the DE interface
running at ULCC has been gathering some figures to try and provide feedback
on information availability and response times.  

The figures for the last couple of days are as follows.  Naturally, they can 
only reflect availability/response times for the bits of the DIT that have
been queried in that period.  They are also purely a view of the DIT from
London.

The columns show the %age queries being
answered successfully (although there may not have been useful results)
within a number of time-bands in seconds, and the %age of failed ops.  For
reasons which are too complicated to explain in a word or two (no - actually
"bug" is the mot juste), the response time figures are probably slightly 
optimistic.  Also note that the totals do not always add up to 100% - this 
occurs in cases where I have availability figures but not accurate 
timing figures.

Hope this is of interest.

Paul
