Thread:Project:Support desk/Formatting and images often don't load

If I load any of my wiki pages, and hit refresh over and over, the page will load with minimal formatting (left aligned, no skin, blue floating links etc) about every other refresh. Half the time, it loads correctly.

I have $wgServer set to the host url prefix.
