The best way to see whether any resource is available, from an NIC to a database to a Web server on the other side of the world, or the Moon, is to try to use it. Any other technique is liable to the timing problem that it was up when you tested and down when you used it, or the other way around. And when you try to use it you have to deal with the failure cases anyway, because they are generally checked exceptions: why write the same code twice?
