Sorry but seems that did not help. sync_info command in daemon shows now most of these nodes (except two - 108.61.220.229 and 207.148.5.250) are simultaneously out of the blockchain. Seems that alternative at 40646 did the damage

Regardless of that, the rest of network is probably synchronized.
Did you delete or replace data.mdb as I emphasized a page back?
It's not my local problem, there is no need to delete my base.
It's remote problem on these nodes.
The rest of network including my daemon are ok.
Now 45.77.89.64 seems also ok, so there are 3 stuck nodes of those 6.
Oh, it seems I am the one that should have read more carefully!

You are referring to external nodes - including some in Speedie's priority network - as still being out of sync. Hmm, we have now reached my level of incompetency so I'll defer to the experts but my suspicion is that this is a non-issue for now, though the only evidence I have for that is my daemon/wallet is still sync'ed up and working fine.
