I know that most of you know that ViaBTC are offering a service to accelerate transactions and everyone seem to send transaction with low fees and use it to make things faster.
I was checking btc.com blockexplorer until I saw an option to accelerate transaction which probably got added recently, I thought I should share it with you.

Unlike ViaBTC though, the service is not free but It's really nothing much when you need to speed up a transaction urgently: https://pushtx.btc.com/

"Cooperating with main Bitcoin pools, we provide transaction accelerator service, which can make the probability of confirming transaction within 1 hour come up to 75% and 98% within 4 hours."
