I travel pretty regularly for work and where I’m at right now is beyond pathetic. It would be nice to compare users experience with internet speed when making a booking decision.
To add to that the overall internet “experience” could be a rating. Some places I stay have decent speed but they boot you off every 6 hours. Some make it extra difficult to log in. Some sneak access in as an optional extra. Some do all three.
The review would stay and hurt their reputation.
Also, if the service you use is in the far east and the damaged cable in the far west, the results would deceive you and make you believe the internet connected to your service is good while it’s not.
The best option is to advertise the maximum speed in rush hours from local or nearby server.
If I’m annoyed by an internet connection, it’s rarely due to one site. Sure, the onward connection is out of their hands, but they have choice of provider and deploy the local infrastructure.
