After our previous router died after a lightning strike, we got a new one. Since that new one was active, though, I had the strangest experience: when my KDE session reloaded my Konquerors, it would often claim the hosts did not exist. That's quite a big WTF, I'd say. For some reason, all DNS requests stopped working over UDP for a small while. (Manually dig'ing with +tcp worked.) Which is pretty annoying if your session also starts Akregator, which also wants to look up lots of hostnames.
