I have the same issue, the IP's causing the error are all from the same ISP. Hughes Network... I'm assuming it's the ISP. Looking back it appears it started the first week of April.

I found a similar thread in adsense help discussion with these htaccess rewrite rules which should solve the 404 problem however I'd like to find out what is the root cause of the issue. I can't seem to find anything elesewhere.

RewriteRule ^pagead/expansion_embed\.js$ [pagead2.googlesyndication.com...] [R=301,L] RewriteRule ^pagead/render_ads\.js$ [pagead2.googlesyndication.com...] [R=301,L] RewriteRule ^pagead/test_domain\.js$ [googleads.g.doubleclick.net...] [R=301,L]
