Me too. Here are some hints
If you're trying to get to Mike O'Connor, try my home page
If you're trying to get to one of the dozens of goofy blogs and wikis I host (AprairieHaven.com, UrbanUsers.com, BugLifeCycles.com, Geezercast.com, SexAndPodcasting.com, 1666Coffman.com, GrinnellWiki.com, SAP.org, etc.) you're at the right place, check the URL and try again.
If you're trying to get to one of my generic domains (eg. Bar.com, Pub.com, Place.com, Cafes.com, etc.) you're also at the right place -- I'm just not publishing anything on those domains right now.
If you're trying an internal company link (or system) that's suddenly broken, it's probably because your systems are misconfigured to use a subdomain of corp.com like "abc.corp.com" or "intel.corp.com". Corp.com is another one of my generic domains and I've gotten a lot of traffic from folks after I set up a wildcard in DNS in mid-June 2009. Show this page to your networking folks -- it'll make 'em cranky but they'll know what they need to do.
