Two leading mining pools in the Bitcoin network, Antpool and BTC.com, begin mining Bitcoin Cash.
The first one to announce the news was Antpool, on August 18th, however, pointing out that this will happen only after one of the pools supporting Segregated Witness reports on Bitcoin Cash mining:
Antpool will start to provide BCC mining option after at least one of SegWit supporters/fan pools start to mining BCC.

Then, two days later, BTC.com reported on mining the first Bitcoin Cash block:

As well as the announcements on Twitter, the data provided by cash.coin.dance also indicates the beginning of mining Bitcoin Cash by the leading pools:

Notably, this Saturday, August 19th, the price of Bitcoin Cash exceeded $900, which, coupled with the Anrpool and BTC.com news, seems to indicate pretty good time for Bitcoin Cash.
