I know there’s at least one other person here who uses OpenOffice.org as their office suite and Virgin Media as their ISP, so you may be pleased to know that Virgin mirrors OpenOffice downloads at openoffice.virginmedia.com. If you’re a Virgin Media customer, then this is the fastest way of downloading it as it should require the least number of hops.
Virgin also mirror all downloads from Tucows and possibly some other sites so it may well be worth checking out before you download, especially if it’s a big download and you’re lucky enough to have Virgin’s 20 MB broadband offering, as you’ll be able to make the most of your bandwidth.
