it's been a day and a half now since i swapped it, and sometimes i can access my site okay, and sometimes i can't. this morning for example it looked fine, but then suddenly reverted back to the parking page as if the nameservers hadn't been changed -- during the same session.
i know that it wasn't a browser caching issue, because my homepage contains today's date.
i'm using sky broadband and i know that they change my IP every now and then, so i'm wondering if they suddenly routed me through something else mid-session that maybe hadn't got round to updating the nameservers yet. sounds a bit wierd to me, though.
