After the restart of the neard service:

WARN sync: Block sync: 1438750/1900059 No available archival peers to request block
....

HEAD detached at 68bfa84ed Tried to delete blockchain and resync from scratch.

I had similar when I purposely tried "archive true" in config.json, but "official" from S3 wget is set like this:

"archive": false

(ignore if this is something else, I think there are just no or not enough archival nodes with complete history running now)

Thanks @stiavnik i will try to re-sync with non archival config (unfortunately, you need to delete data and re-start sync process). In the past it was required to switch node to archival mode, so I did it as usual during migration from the forked chain.

I confirm that resync after setting archive to false worked for me. Looks like there is no more archival nodes. Thanks @stiavnik
