The Planet nameservers down?

I made some reverse DNS changes about 9 hours ago and they still don't seem to have propagated. A quick search with the "Reverse DNS Lookup" tool at http://www.dnsstuff.com reveals the following result:

> How I am searching:

Asking f.root-servers.net for xx.xx.xx.xx.in-addr.arpa PTR record:

f.root-servers.net says to go to figwort.ARIN.NET. (zone: xx.in-addr.arpa.)

Asking figwort.ARIN.NET. for xx.xx.xx.xx.in-addr.arpa PTR record:

figwort.arin.net says to go to ns2.theplanet.com. (zone: xx.xx.xx.in-addr.arpa.)

Asking ns2.theplanet.com. for xx.xx.xx.xx.in-addr.arpa PTR record: Error: ns2.theplanet.com reports a SERVER FAILURE.

Answer:

An error occurred: Server ns2.theplanet.com is reporting a server failure (it is probably broken).

Would this be affecting the RDNS changes? The nameservers have been down for a bout 4 hours so far if I'm not doing something wrong here! Anyone else got problems?
