The developers of OpenDNS claim that the service makes Web surfing faster, but under normal conditions, any speed improvements it gains are nearly imperceptible. Certainly I didn’t experience a big change in service speed, nor any of our clients going to be bowled over by vast speed increases.
Why? Because overall data throughput still has a much larger effect on surfing speed than name resolution. It’s also worth noting that when name resolution doesn’t work, you simply can’t surf at all.
If your ISP is unreliable, you might at least try OpenDNS to see if your surfing woes are related to a DNS problem it can solve. Fortunately, OpenDNS is free for personal use and easy to remove, so you won’t suffer buyer’s remorse if you install it and never really notice what it does.
