Very funky… I generally use Chimera, which is a Mac (OSX only) browser based directly on Mozilla’s gecko rendering engine.
Yesterday, I tried lambdaiota.org with it, and got the non-redirect condition (ended up at one of those registrar “coming soon” pages). Worked fine in IE on the same computer.
Today, however, lambdaiota.org is definitely redirecting properly to http://lambdaiota.burlyweb.com/ – In IE, Chimera, and Mozilla.
I don’t know what changed or why, but it’s ok now and wasn’t before…
Edit: I also noticed both days that on the first redirect the calendar script seems to choke with an error; if you reload or on subsequent connects it displays properly.
