i've been getting this for the past day or two. it only shows up on specific pages, though, and its repeatable on those pages. for example, page 1 of the
Random Pictures thread works just fine, but page 7 gives me a 502 error.
the same threads that were giving me 502 errors last night are still giving me the error last night are still giving me the error this morning, and likewise the threads that didn't give me the error last night are still not giving me the error.
