I’ve just started using Warp+ and it has been excellent for my specific use case: better peering to my Plex server while in another continent. Plex was unusable and now it’s not. Overall very happy despite this brief outage.
You can't use Warp+ to control your egress point, unlike many other VPN services, so you can't use it to bypass geographic blocks. However, since Warp+ (not Warp) routes you within Cloudflare's network (using their Argo routing from participating datacenters), I'd guess GP gets a more stable and faster connection to their server than the public internet would provide.
