sitelutions stopping free dns redirection

One of the sites which had a domain redirect stopped working, and found that sitelutions.com had stopped their free dns redirection. "In October, 2014, after offering free DNS and redirection for about 14 years, Sitelutions was forced to shutdown free DNS and redirection. Over the years, the free services began to attract a significant amount of abuse, including very large DDoS attacks. These attacks would impact the services being provided to paying customers, and were very expensive to properly mitigate."

Shifting some domains to nettigritty nameservers (which were purchased via nettigritty.com), some to freedns.afraid.org and some to cloudflare dns.
