Yesterday from about 2pm to 8pm Aust EST, my ISP had some serious routing problems. This, unfortunately, isolated my network from vast tracts of the Internet for the duration. Some people could get to my site, whereas others could not. As far as I know, locally TPG, Internode and IInet subscribers would have been unable to reach my site, but Optus and Bigpond subscribers could. International ISP's seemed to be very hit-and-miss. I have no idea what went pop for my ISP, but it was intensely frustrating! Apologies to anyone who had mail problems with my site or couldn't access the web site.
