Eucalyptus problems on India and Sierra

Are there any known problems with running Eucalyptus on India and Sierra from 4/5/2011 to 4/7/2011?

Here is e-mail from a user:

Ryan,

FYI, we cannot launch instances in India for the last 2 days. For yesterday on Sierra, the EBS we created cound not be mounted and we might have lost the data we stored there. For some instances we launched, they terminated themselves after a few minutes.

We did not capture specific commands we used because they were the usual ones for launching instances.
