I am a web developer, ColdFusion programmer, dba, software architect, and systems and network administrator through my consulting business, Ziggy Consulting.

I used to own and operate DtDNS, a DNS hosting and management service with a focus on dynamic DNS services. I started DtDNS in March 1999 and sold it to another company in February 2011.

I also love to fly since I earned my private pilot certificate in 2008.

My primary work is web development with ColdFusion, but I also manage networks of remote thin clients deployed as kiosks, a number of web servers at various locations, and a small data center for a web development/hosting company.

comment Is it possible to completely avoid a single-point-of-failure in a web back-end?
You are correct that using DNS for load balancing (via round-robin) or for failover is not an optimal solution. It is a cheap solution, however, if you can't afford to do it properly. Even if you keep the TTL low enough to make manual (or automatic) changes to point to a different IP/provider, some DNS resolvers will just ignore it and keep the information cached longer then you specify anyway. The bottom line is that if you're experiencing downtime often enough to need to jump through these hoops, you're likely better off paying a little more for a better hosting provider with better uptime

That depends on how that IP address has been deployed. If it's a single IP to a single box and that box fails, then it would be unreachable. If it's shared among multiple boxes and one of them fails, then it would still be reachable. (For example, I have a pair of linux-based firewalls that share an IP; if one fails then the other will see that and take over automatically; this will all depend on the equipment you have deployed). If it's deployed to multiple locations using IP anycast, then the failure of any one location can still be survived.

Unfortunately if they have an issue with their border router or Internet provider, nothing you do on the server is going to help that.

comment Suggestions for accessing SQL Server from internet
If you have to go put hands on it, perhaps install GoToMyPC on the target computer and see if that will work as a remote access solution. It's similar to CoPilot OneClick but from a more well-known vendor, doesn't require ports to be opened or keeping track of the IP address.

comment Web server minimum password security based on 100 attempts per second
I agree it can be annoying, but if the lock is temporary (say, 20 minutes) then depending on how often users are authenticating it may or may not become a problem. It can also be a great way to identify user accounts that are being targeted and monitor them more closely if an account is being regularly locked out. Comparing the origin IP addresses for good vs. bad attempts can also be a good way to dynamically lock out ranges of IPs if one subnet is continually locking the account.

As an aside, be prepared to lose that first domain as part of a UDRP complaint. That is a pretty blatant trademark violation.
