Blockexplorers like Blockchain.info have their own mempool and transaction index list. For unconfirmed transactions like the one stated, they are stored in the mempool. As with other nodes, each individual mempool have their list of rules and they accept only transactions which fits those rules in their mempool.
The most common reason for the discrepancy is with the rules, more specifically the minimum fee for it to be accepted. The transaction has too low of a fee for it to meet Blockchain.info's requirement. It doesn't mean that it wouldn't be confirmed. Once its confirm, it would appear on all of the blockexplorers.

But if you look on blockcypher, blockchair, oxt.me, etc. it's visible?
