php.net frequently hangs

Lately, I've noticed a significant slowdown whenever I go to access content on php.net. Finally remembered to catch some of it today: http://us3.php.net/cached.php?t=1421837618&f=/js/ext/modernizr.js 854 ms http://us3.php.net/cached.php?t=1421837618&f=/js/ext/hogan-2.0.0.min.js 1,852 ms http://us3.php.net/fonts/Fira/woff/FiraSans-Book.woff 1,666 ms http://us3.php.net/fonts/Fira/woff/FiraSans-Medium.woff 1,887 ms http://us3.php.net/fonts/Fira/woff/FiraSans-BookItalic.woff 1,932 ms http://us3.php.net/fonts/Fira/woff/FiraMono-Regular.woff 1,993 ms http://us3.php.net/fonts/Fira/woff/FiraMono-Bold.woff 1,994 ms ~90% of the times listed above are spent waiting on the remote host to respond. I'm not sure why static content would take 1.5+ seconds to start delivering unless Apache is somehow hitting its max connection limit. Total time to load the page when the site gets stuck like this is ~20 seconds. If I'm impatient, I can try again and it usually loads the page right away.
