From time to time altavista.se will produce results from the av.com index instead of its own. Quite often as of late. My guess is that they havenít got the capacity to meet demand. When they get overloaded they just transfer requests to the more powerful av.com.
A bit frustrating as they give completely different results. Different index and different algo at random. Totally unpredictable.
Anybody else seeing the same on other local versions of av?
You bet. I was just talking to Seth Wilde about this and will post something in the AltaVista forum [webmasterworld.com] Really mysterious, but what I saw is the direct opposite from what you have seen. They seem to be weeding non dot-coms out of their main index, probably updating national indexes frequently as a result. That might account for the irregularities that you have observed. Looks like Europeans had better get dot-com addresses for anyhting in English. Time to split multilingual sites into parts, with a different address for each and English in dot-com.
