Hmmm... I just tried it and had no problems accessing the web page. Are you going to mobileme.com?
Something kind of interesting happened though. Both the map on mobileme and in gps on my iphone have my location (work) off by roughly a mile. I've used the map and find my iphone from work and had the correct location so this is strange. I guess I'll check back later in the day to see if it's still off.
Edit - I used the site to see where my iPad is at and it has the correct location. I rebooted my iPhone and location is still off. It's different than it was before the reboot but still off.
This is because of the new location policy. Your iPhone is going off the Tower that it is connected to, whereas if you're using a WiFi connection it should show you where that access point is.
Also, if you're a developer like me, iCloud takes over your MobileMe, so you have to access icloud.com rather than me.com for Find My iPhone.

Nothing about this is correct.
