100 sat/B is way to low for the current status of the network. Check
https://bitcoinfees.earn.com/ for an appropiate fee the next time.
With the current fee your transaction might never confirm (or at least mostly not until the backlog of transactions has cleared a bit).
Additionally it seems like not every node has your TX in the mempool. Blockchain.info for example doesn't find your transaction, whereas blockcypher knows about your TX.
