The Internet blackout in Egypt serves as an excellent case study for the kind of disaster any IT department should be ready to face. Backup systems must be in place for the day when servers crash, a fire wipes out a server room, an earthquake destroys the entire business site, or in the case of Egypt, the government decides to shut down the Internet. But what about the road warrior?
It also does not take a government Internet blackout or a major disaster to create the need for a dial-up connection. How often have you ever been in a hotel room with spotty Wi-Fi access and no Ethernet port? In the office, DSL and cable broadband access from major carriers do go down sometimes as well (although larger firms should have Internet provider backup options available, but many SOHOs will likely not have the resources to do that). Then there are electricity brownouts, and for SOHOs without any backup power generators, broadband will not work.
Access to a landline phone, a modem, and a dial-up-Internet ISP account is all you need to get back online in all of the scenarios described above. When there is an electricity outage, for example, the telephone lines usually still work, thus making a dial-up connection possible.
Without touting the merits of any one product or ISP service, here are some dial-up alternatives. It’s still possible to buy laptops with internal dial-up modems, although the feature has become less common following the proliferation of broadband access. HP says it still offers internal modems for its business customers, for example, for when broadband access is unavailable or in the event of a disaster.
When traveling abroad, you must remember to bring the right power adapter for different electrical outlets in various countries around the world for your laptop as well as an external modem. To that end, USRobotics Courier 56K comes with 110V-to-240V power supplies with different adapters.
Dial-up connections require servers, which some ISPs provide. Among the major carriers, Verizon offers the service while Cox Communications does not. Other dial-up Internet providers include EarthLink, NetZero, and PeoplePC. While there are usually ways around it, many business users who do not have the patience to hack their systems can rely on the software the service provider offers when connecting with a Windows, Mac, or Linux operating system.
However, one thing to keep in mind is that users are charged phone rates. Dialing up a server in California from a hotel in Egypt is likely a costly proposition.
The data transfer speeds of 56 kilobits-per-second (Kbps) that dial-up connections offer are hardly any match for a 4 megabits-per-second (Mbps) broadband connection, of course, and thus are painstakingly slow for bandwidth-intensive applications such as Youtube. However, for Twitter, Facebook, Google, or e-mail access when disaster strikes or broadband is unavailable, a dial-up connection can get the job done.
