Sellers with multiple "availability zones" in London for a Wordpress site?

I'm looking to launch a wordpress site and I'm looking at GCP or AWS because uptime is of primary importance and having strict redundancy boundaries in the form of zones is helpful for this. Of course, this sends the budget through the roof.

Does anyone here in London have a similar concept? Equivalent cost is $100-200/mo on 3 VPS with 2 CPU and 8 GB ram each on GCP otherwise.

2 zones is minimum, 3 is a bonus.
