For your information, this "stable/unstable" situation is seen differently
depending on where you are.  
For example,
 - our pTLA site (VIAGENIE) is connected directly to merit.
 - we've been very careful since 6 months now to look at the merit 6bone
reports and debug things when we appear in the report and fix things. For
this, this report has been very useful (thanks to merit guys). We also had
the opportunity to debug MRT many times. We even found bugs in the v6
kernels of some implementations that keeps our routes forever in the
kernel. The consequence is that most of the time, our site is very stable
and do not appear instable in the merit report.
 - but, the cselt guys from italy just reported at the last ietf that our
site was unstable. We haven't seen those problems. 

In conclusion, it seems to be very related to where you are. 

Regards, Marc.
