The subnet in the README is restricted from being freely deployed to

[ByronBecker]

We can't deploy to jtdsg-3h6gi-hs7o5-z2soi-43w3z-soyl3-ajnp3-ekni5-sw553-5kw67-nqe because it isn't openly allowed yet.

We are migrating to another subnet: bkfrj-6k62g-dycql-7h53p-atvkj-zg4to-gaogh-netha-ptybj-ntsgw-rqe

This one is open to anyone and is really easy to locate since it's the European subnet.
