I had a quick look at the latest issue of PC Plus (Issue 238, January 2006) yesterday in my local supermarket and stumbled on Dean Evan's column about 24MB ADSL2+ connections becoming mainstream by 2006 and pointing to the fact that some of these services come with strings attached.
With my previous, unfortunate experiences in mind (see my post "Useful tips for dealing with difficult ISPs" ), I was glad to see that someone knowledgeable agreed with me regarding the fact that broadband is now so cheap that it makes plenty of sense to get two connections; just like with the expensive ISDN lines that populated the pricelists of BT et al some years ago.
Getting a second broadband line (or more) makes a lot of sense especially if you use the lines judiciously. Legend Communications, for example, has a load balanced broadband access offering, where you can combine several broadband circuits into a single one, and if anyone of these circuits breaks down, it is seen from a user point of view as a decrease in speed rather than a complete system halt. You might see that some also advertise the service as Bonded DSL.
I strongly believe reliability is what companies should be looking at, rather than being obsessed by cost. Stitching together several broadband lines, or bonded broadband, combines the best of both worlds.
This method is cheap, readily available, easy to implement and almost failure-proof - provided you follow some simple steps. There will be more on this as I try to get some more details about how to get that solution working.
