Probably yes. I checked the blocks history and the pool seem to had a lot of orphans around the time you sow this fall and many hours before that. This however doesn't seem to be an issue with the network but with their pool, my pool had just 1 orphan in this period.
yeah I also am having problems with
www.ravenminer.com the page stats for my miner are not matching payments received ,
and missing payments, for the last 4 or 5 hrs , seems like they are having some issues, I have been hoping they would get it together
since the (Hack) and I took the loss like everyone else, I see on discord other Miners are having problems too,
