Most ISP's block port 25 as well.

Its not a horrible idea if done for testing or personal use.

But for a production server, or one you plan on profiting off of it seems like you made a good choice to go co-located.

Well, then I need a 24x7 online PC. But I'm still horrified what I will do when the power cut happen!

You can get a cheap dedicated server in a decent datacenter for as low as $45 a month. Hard to beat that. Also, web servers need uplink speed, and DSL/Cable has very low uplink speed. Go with a colocation or dedicated on a 100mbit line.

Colocation is definitely the solution. It's always best to let someone else handle the environment, infrastructure, and headaches of dealing with logistics. This is especially true if it's just one server. You can co locate a server now for less than it costs to have internet in your home.

Agreed Colocation is a better idea.. If your looking for a good colocation facility I would suggest looking at ColoUnlimited for $49 a month you can get 2U rack space, 2Amps of power and 10mbs unmetered bandwidth.

Their connectivity and support are top notch.. I have had a server in their facility for over a month and have put them to the test. Even called them at 4am on New Years eve to assist me with something and I got a tech with in 3 rings.. And 20 minutes later all was fixed.

They are located in Dallas,TX and are owned by the same company that owns CoreXchange.

I would not even try it, it is a big risk plus very expensive.

Just not good idea at all unless it is for a personal thing.
