How Much Does Your Work Depend on the Internet?
malord asks: "I work for a small company that has recently had problems finding a stable internet connection. It started when we moved our office in order to upgrade our connection speed. We decided to go with cable internet through Comcast, since they offered the best speed for the price and told us that it would be available before we moved. Unfortunately, Comcast did not provide any service for two months after we moved, so we piggy backed on an existing (slow and unreliable) wireless account with another company in the meantime. When Comcast finally came around, the service that was provided was far from adequate with a consistent 30% packet loss and multiple disconnects everyday, which was confirmed through Comcast's tech support. Throughout this process, we have realized that having a reliable internet connection is more important than having a phone line and almost as necessary as electricity. What would you do if your internet was suddenly like dial-up for weeks at a time? How much money would your workplace lose if it was out for an hour or an entire day?"
Have you heard of an MX? Let me explain this one to you then. Your ISP should act as an MX, or Mail Exchange for you. IF your connection goes down, the mail servers around the world would then try your ISP next (since you have multiple MX records). Then, when you connection is restored, the ISP's mail server (Sendmail, Qmail, the guy in the back room doing.. .umm... it involves online videos...) would send all the pending email in queue to you.
This is why Mail Exchanges were created. Unfortunately too many companies do not employ, nor are they offered a very good backup MX. Email delivery is VERY reliable, IF YOU HAVE A BACKUP MX!
