Hurricane electric offers free dynDNS, free DNS, and also free IPv6 tunneling. https://dns.he.net/ You can even set up an IPv6 tunnel for a dynamic IP and have it update dynamically.

Our experience is the opposite. LA to Denver and at least once a week Nagios goes batshit because packetloss pops up to 8% on and off for hours. Partly this is because our unfortunate choice of ISP, IPTP, doesn't understand how BGP works and localprefs HE over everything. But consensus seems to be that they're just overloaded.
I suppose selling for a third or less of other ISPs tends to increase network demand.
