"live.com 当了" 的翻译可以是 "live.com has been used as" 或者 "live.com was set as" ，但是这句中文表述不太完整，如果能提供更多的上下文信息的话，我可以给出更准确的翻译。你可以补充更多信息吗？

I was just about to check if IE7 has been officially released today, and when I opened live.com, it was down. Screenshot: http://static.flickr.com/81/273119355_5e21c6ead3_b.jpg
