Beware of Freenom DNS

If you get a free domain name on Freenom, it may be tempting or more simple to use Freenom's DNS. However, Freenom DNS is extremely buggy, slow, and broken.

I used to use freenom DNS. Sometimes, my site would return randomm 504 or 502 errors. Furthermore, when editing DNS records, the DNS page itself would crash or return errors. Therefore, if you want a reliable, fast DNS, just use Cloudflare. It's worth it.
