https://live.blockcypher.com/btc/pushtx/ continues to accept the TX - but only holds the TX in their mempool for about eighteen hours, so there are occasions when the rebroadcast misses a couple of hours.
If you had the IP address of any of the nodes that accept this transaction you could directly send the tx to them without needing to go through a block explorer.
P.S. The IP address shown on blockcypher (3.95.194.185) is not reachable.
