To quote the usual line, I can't reproduce that on this end. It goes white and won't load css for days at a time, not a matter of minutes. The last time it happened to me, it didn't go away for well over a week.
This time it was happening on both my home and work computer, the two use different OS versions, different anti-virus and as far as I know have different service providers. It happened on all the browsers I tried, including IE with a basic install. It was happening on both Wowhead and Alla. Something is seriously bollixed, about the only thing I forgot to try was switching to Linux.
In Chinese: glasses are yanjing; eyes are yanjing, and the beer of Beijing is Yanjing. When speaking, the difference is in the tones. Did I just order a glass of beer or a glass of eyes?
