I had trouble sending some e-mail during the last few days – messages were being returned as undeliverable, but it was hard to understand why. A couple of other people have mentioned the same thing to me. I don’t know for sure, but this article about a squabble between two major Internet service providers may have the answer. When a critical link between Cable & Wireless and PSINet was cut after some negotiations broke down, a side effect was that parts of the Net became inaccessible for some people. E-mail was bouncing all over. It’s supposed to be over now, although the article’s point is that the same thing can happen again.
