Impossible to get SP Lab Dates in Europe!
Hmm, SP seems to be very popular at the moment – I looked yesterday for a seat earlier than my current October Date and got some options in December – I went back in today and NADA.

From experience there are 2 seats in Brussels for SP out of about 26 seats total. There are 4 Voice I think and the majority RS [maybe 12 or more!]
Regarding the latest changes announced to the RS Track if I were an RS candidate I would not worry too much as they will not be in depth questions on the MPLS L3 Section as that is covered in the SP Track. Troubleshooting, I enjoyed in my SP Lab and it will be interesting how they handle scoring the TS Section prior to proceeding to the Configuration Section. Regarding the SP Blueprint, since Security went to V3 in April 2009, Voice changing in July 2009 and now the RS announcement effective October 2009, I guess an SP Announcement is in the pipeline – Nevertheless, they will have to give SP candidates 6 months notice of upcoming changes as per procedure so if your SP Lab is currently booked you should be fine!
