They are not wrong. The two links exist for different reasons. Pacific/Samoa is a current-style name, and is flawed due to ambiguity. It therefore links to the now-preferred more specific name. US/Samoa, on the other hand, is a name from an older naming scheme. We don't use "US" as a top-level component any more. All such names are now links. Historically, US/Samoa referred to American Samoa. When the new naming scheme was introduced, presumably the zone was renamed to Pacific/Samoa, with US/Samoa becoming a link to it. Then when the ambiguity was discovered, the zone was renamed to Pacific/Pogo_Pogo, and both of the former names became links to it. -zefram
