Chart of YC companies' hosting decisions, 2010 edition
Very surprising so many people use Godaddy for their DNS,  given it is very slow as far as DNS servers go.  I've been running a Pingdom speed/reliability test for a few popular DNS servers for the past few months, and here is the data:  Guide:
      
  
  October:
  Godaddy DNS	100.00%	0h 00m 00s	0	68 ms
  Dynect SMB	100.00%	0h 00m 00s	0	31 ms
  DNSMadeEasy	100.00%	0h 00m 00s	0	39 ms
  
  November:
  Godaddy DNS	100.00%	0h 00m 00s	0	67 ms
  Dynect SMB	100.00%	0h 00m 00s	0	26 ms
  DNSMadeEasy	99.98%	0h 10m 00s	1	43 ms
  
  December:
  Godaddy DNS	99.99%	0h 05m 00s	1	58 ms
  Dynect SMB	100.00%	0h 00m 00s	0	28 ms
  DNSMadeEasy	99.00%	7h 25m 00s	22	40 ms

So basically Godaddy DNS is reliable but slow, DNSMadeEasy is relatively fast but had some uptime troubles in December, and Dynect (Dyn Inc) is fast + super reliable.As for pricing:- Godaddy DNS is free (I think?)- DNSMadeEasy runs about $2-5/month (max of 10 million queries/month)- Dynect SMB runs between $30-95/month depending on what you need (max of 1.8 million queries/month)
