Call for help: 3rd party providers of backup NS?

[aklist_bind at enigmedia.com]

Hi All: I just lost a remotely-located primary NS for about 100 domains. I 
have one box acting as secondary at another location running off of a DSL 
connection with a static IP.

Losing the primary made me realize how vulnerable I am in this scenario. It 
will be a couple of days before I can get the primary server up and running, 
so I think I'll be OK before the TTLs expire, but if the second server or 
it's connection go down, I would be in big trouble.

I'm wondering if anyone can recommend a 3rd-party org that provides backup 
NS? Or, is anyone out there that would be willing to exchange secondary 
services with me?

Or, would anyone be interested in providing secondary services on a 
temporary basis, to help out a fellow list-member <g>?

I'm also looking at my options at this moment...is it a good/bad idea  to 
backup my current named.conf and then edit it to make the secondary a 
primary for all it's domains? I'm thinking that I could do this pretty 
quickly just by renaming all the backup files and editing named.conf.

Thanks in advance for any ideas or expressions of condolence!
