The last database dump on

from March 9th, almost
one month ago.
Is it correct therefore that we have no backup for data written after that
day? Or is there some other backup strategy at the colo?

We have several (three?) databases receiving content replication. So
even if 2 servers totally crash at the same time, and 1 can not be used
for whatever reason, we will still have 1 working copy.
ASCII schema is something like:
--> Slave #1
/
Users -> Master Database -----> Slave #2
\
--> Slave #3
As for regular dumps (aka twice per week), stats generation ... I think
we wait for a monster server (read more disk space).
