I finally traced down serious problems I was having with my internet connection to this plugin. Making it's links to cached web pages (nyud.net) and what-the-heck else it's doing (preloading pages? I have no idea), it's making hundreds of DNS requests for every search done. This actually floods my DNS server, as seen in Wireshark, and therefore prevents pages from loading. I was getting 404s every 3 or four minutes before I disabled this script. I went back in and edited out the parts creating cached links and so far (ten minutes in to testing) it seems to be doing better.
