Zerigo no longer offers Free DNS plan

Just got the email yesterday.

Going to spend Saturday transferring DNS records and migrating name servers.

The only reason I had set up with zerigo to start with was because my friend's registrar only allows name server access, and zerigo was free and easy to use with Heroku.

I'm a bit miffed at the short notice before an essential service is terminated. I would have appreciated having until the end of Feb to make DNS management decisions and ensure the name server migration goes well.

I use a zerigo free DNS plan and have not received any indication of a change in support of this plan at this time.

Edit: Just received an email. "If you would like to continue to utilize Zerigo DNS services, you must convert your account to a paid Zerigo Virtual DNS plan by January 31st, 2014."
