Note: I was going to post this on individual platform discussion threads, but it's neater to post on a dedicated thread, even if short-lived, as it likely affects all platforms, even if there are slight differences as to how.
The increase in ITV HD regions has had a knock-on effect on not just the number of SD and +1 regions, but now ITVBe+1 apparently. It's also closing on 13th April with some of the SD services.

Though this just mentions Satellite, I can't see the point in keeping the LCN placeholder on Freeview, which just shows an hour a night in the wee hours, or keeping it going on Virgin Media, where they recently moved it to 162 in Scottish areas as a result of requiring PSB channels to be in at least Top 20 EPG positions and BBC Alba taking its slot. ITVBe+1 may as well be closed everywhere, Satellite was bound to be its biggest audience and that's the feed that's definitely closing.
I'll post on the relevant changelogs when changes occur.
