The silver shortage is bunk. They were doing pre-sales for October release.
It begins to look like the Mint is actually trying to fix its website problems. Instead of Joes Garage and Hosting service, the front site is now hosted at
Amazon and they have Cloudflare (regardless of what you think of them) in front of the web store.
HOWEVER, testing a web site for scaling is not an easy project.
You first need to define the shopping journey. Since they are tuning a very specific problem, that's easier than it might be for a generalized eCommerce effort. Then you need to define your goals - i.e. 100,000 users attempting to purchase item X in 5 minutes, with only 1% being refused due to site problems.
Then you create scripts in one of a handful of tools that simulate web users.
Execute the scripts. If you reach your goals, you are done. If not, you analyze the site information, make the tuning changes, and execute again.
You may need to push static content (like images) to a content delivery network (CDN) - keeps traffic off your network links and reduces the load on your servers.
You may need to scale horizontally - bigger server. Or vertically - more servers.
You might need to do a variety of tunings of your database.
Even change platforms - switch to a lighter-weight web server program.
Or all of the above.
This is typically a project lasting several months.
Or you can do nothing, as has been suggested above and hope fewer people show up to the party. Which is my bet.
