The Universe, http://www.netvibes.com/cmb was -at one moment- almost empty and at least half of our tabs were gone (as in deleted).
I got the biggest scare of 2009 so far ...
After a few minutes, and re-loading the site several times, logging out and -in again, all 150+widgets appeared to be listed in the Tab "Lost &Found".
They really mixed my web up ....
That was sort of a relief. I emailed Netvibes Support and started to make emergency repairs, but made sure I got copies of that Lost & Found tab first.
Next morning after a bad night sleep, all tabs were restored, including my newly made repairs.
The response of Netvibes Support was received very soon:

It is good to know. Now you know.
