Sorry! An "expat" or "expatriate" is someone living in a country that they're not a citizen of. Living in this context, you hear it a lot, but I forget that people don't use the term much in the States. :)
To explain a bit, large computer networks owned by companies get allocations of IP ranges that they need to announce so other systems know where that IP (and any services/websites using it) are.
Sometimes they announce a smaller chunk of IPs than they ought to (ideally they announce the whole big chunk they got allocated, but often companies still announce lots of little ones) which might end up filtered by other networks e.g. your ISP in an effort to keep the number of announcements they know about down to a reasonable number (the equipment can only handle so many you see and so many small chunks announcedcan = way too many on global scale).
There can be other issues too that can cause your ISP not to have a route to an IP e.g. whatever range LJ uses, but if you get the issue that it's accessible from elsewhere/another ISP but not from your ISP again then it's worth letting them know and bugging them to work out what's going on.
