I don't know personally but in situations like this I like to try to look at things logically.
If a site has one or two broken links then there would be no sense in penalising it for this since the links are not directly in it's control. Broken links like this are a fact of life in the Internet.
If a site is old and it has several broken links it would be logical to conclude that it has not been updated for a long time and that it should be downgraded as a result.
