July 18, 2003 -- (WEB HOST INDUSTRY REVIEW) -- Cisco Systems (cisco.com) revealed on Thursday that Cisco routers and switches running Cisco IOS software and configured to process Internet Protocol version 4 (IPv4) packets are vulnerable to Denial of Service (DoS) attacks.
Cisco IOS versions 11.x and 12.x prior to 12.3 are affected by the vulnerability. Cisco devices that do not run Cisco IOS software are not affected.
Devices running only IP version 6 (IPv6) are also not affected.
Cisco has issued an advisory and made software available, free of charge, to correct the problem.
According to reports, the situation has worsened due to the release of the exploit code on a full disclosure mailing list. The concern now is over how much damage can be done before system administrators can update their router software and counteract the vulnerability.
In an update posted today in its advisory, Cisco confirmed that this situation has been brought to its attention.

October 2009 - Web Hosting's All Star Team
This has been, for us, one of the most interesting, exciting and challenging build-ups to an issue of the magazine yet, Web Hosting's All Star Team. The balloting process was our first experiment with a kind of user participation we're planning to do a lot more with in the months to come. We had thousands of ballots submitted, with hundreds of write-in suggestions and a demonstration of user engagement that has us feeling super positive about the project.

July 2009 - What am I Worth?
One of the interesting luxuries of working on a project like the printed WHIR magazine is that it allows us to play with things like our point of view from one issue to the next. In recent months we've been giving added attention to the kind of practical and applicable advice aimed at smaller hosts and resellers. This issue carries on with that point of view, asking, in our cover story, "what am I worth?" It's a complicated question without a clear-cut answer.

May 2009 - The Blueprint for a Small Web Host
I was a little surprised by how difficult it became to see this idea through. We set out to assemble a blueprint for a small hosting business, but butted up pretty quickly against the general impossibility of covering all the territory that was out there to be covered. The basic constraints of a printed magazine, and the less-than-infinite amount of time we had available forced us to face the fact that we could never produce an exhaustive guide to starting a hosting company.
