Only seen SBS3812E spamming on 10 since Saturday... No news of
SBS3807X on 10 so far after it replaced SBS7661Y temporarily for
maintenance. SBS3818P was also a temporary replacement for the perm
buses (SBS7671T and SBS7676E) when they went for maintenance, thus
going over to 518 (since it was technically BNDEP SP) after
that.
For BBDEP side, SBS3816U could be perm, though random BBDEP DDs
appear on 10 nowadays... So far, many perm BBDEP DDs have been
missing from 10. Only ones I see these days are SBS3041M, SBS3087G,
SBS3088D and SBS7658H.
I think 3812E not Sv.81 perm. I still consider all both 3807 n
3812 SP like running ard like SP!
