I ended up using confirmtx.com

Did not happen automatically within 24 hours, their email support is wrong when you use coinpayments gateway, found the guy on this forum. He said he would check it. It got confirmed some 12 hours later. Wheter it was him or just a random miner picking it up is impossible to tell.

Summary is: it happened 11 days after being broadcasted.

The scary thing is that the network did not drop it. I would much rather prefer if there was a hardcoded limit when transactions get dropped.
