Hi Saurav,
Yes, Nanodash at
petapico.org was having problems over the weekend. Now
it's up again. The disk ran full at some point, but I am not sure
whether that was the cause or a symptom. So, I am not sure it's fully
resolved or not...
In any case,
petapico.org keeps making troubles, so you might better be
using one of the other Nanodash instances such as
https://nanodash.knowledgepixels.com/
You can currently not supersede a nanopublication from a different
instance, but you can create a new one on a different instance with
"edit as derived nanopublication" and later retract the old one.
I hope that helps!
Regards,
Tobias
