Google Cloud have suggested that from April (now pushed back to July) people will be billed for the use of static external IPs (approx £2.50 per month per IP). However, the following Reddit page (https://www.reddit.com/r/googlecloud/comments/cswg9g/will_my_free_microvps_start_cost_money_2020/) suggests that this is not applicable to Free Tier, but I can't find any explicit information that can confirm or deny either way.
I had thought this was true as I was not being billed for this in April, but given the recent notification that this will start to take affect from July now (and not April), I am wondering if the lack of charging was due to the date being pushed back and not in fact the free-tier allowance.
Can anyone point me to any evidence that can answer this categorically?
