PageBlaze is described as being "Globally Distributed", which means it has all the "back-end" services (databases, etc.) deployed in three geographical regions: US; EU and Australia. They're all identical, with changes to the database being replicated within a few milliseconds.
When you visit
https://pageblaze.warrilow-apps.click, one of the back-end services automagically selects the nearest region to you using "network latency". In simple terms, network latency is the time it takes for information to go from your device to a server and back again. The lower the latency, the better the apparent performance of the website.
Based on where you are in the world, you will be redirected to one of three sites:
https://pageblaze-au.warrilow-apps.click,
https://pageblaze-eu.warrilow-apps.click or
https://pageblaze-us.warrilow-apps.click.
If one of those sites is down, e.g. for scheduled maintenance, you will instead be redirected to one of the available sites. (This is called "failover".)
You can bookmark and visit those sites directly, but bear in mind that you won't have the advantage of automatic failover.
