I've been using Point as my DNS provider for some time now, but somewhat recently they were bought out by Copper.io. I don't know anything about these guys, but I've been burned by being the client of a bought-out company before, so today I decided to proactively jump ship to another provider. I wanted to stay with a free provider, and so after asking around I've decided to go with CloudFlare.
Already I can see an improvement, with DNS lookups taking anywhere from 1/2 to 1/3 as long as they used to (50-75ms with CloudFlare vs 140-150ms with Point). Not that I expect that will really be noticeable, but hey faster is faster!
Anyway, since I changed DNS providers I've had to go and update PDDNS to support the new provider. So if you've been looking for a decent dynamic dns updater to use with CloudFlare, give it a try!
