You wont want to disable 2.4 and 5GHz on wifi 7. The reason it gets so much higher speeds than 6e is that it can send data on all 3 spectrum simultaneously. If you turn off 2.4 and 5GHz you would essentially be limiting yourself to 1/2 speed.
depends on how many services you plan on running, i think the i3 would be sufficient for what you listed, the i5 would give you room to grow.
the i7’s usually aren’t worth it for servers since they are just a clock speed increase.
Migrations take time, it was never going to be a flick of a switch. Reddit content will slowly get worse and worse, and Lemmy content (or some other competitor) will get better and better as more people move. it’s those core users that generate great discussion that matter the most and those people are looking for somewhere else.
AWS has multiple teirs of storage options in s3, some replicate and some dont. by default those that do replicate do so in multiple availability zones, but not across regions. unless you turn on cross-region replication (CRR) which is an additional charge.
So, for example without CRR if your bucket is in us-east-1 and 1 availability zone goes down you can still access the data, but if all of us-east-1 is down, you cannot.
