First, I would test the internet speed.
https://fast.com/ ('show more' gives detail view)
Then I would use mtr to check the quality of the connection to getsol.us. The hotspot.txt file being checked is located on this domain.
Run these two tests on all machines at the same time when you see the message.
You can deduce a lot from this: connection available, latency, packet loss, etc.
mtr is present in the repository
$ sudo eopkg it mtr
$ mtr getsol.us
However, one must be cautious with all statements here. Solus relies on a CDN network. This distorts some of the data. Globally, it's not as meaningful. The hotspot.txt can therefore be located anywhere and in a different location for each of us...with different connections, speeds and accessibility
A CDN, or Content Delivery Network, is a geographically distributed network of servers designed to deliver web content like images, videos, and files quickly and efficiently. It achieves this by caching content on servers located closer to the end-user, which reduces the physical distance data has to travel and improves loading times. CDNs also help balance server load, improve website reliability, and protect against attacks like DDoS.
