Incredibly often, it seems that Safari fails to load a website. It happens both on my Mac and iPhone and has been happening for a long time. I think this has to do with my WiFi, but I fail to see anything unusual in my Ubiquiti setup.

Anyone seeing similar issues with Safari, or is this some issue in my Internet setup?

(Yes, I've tried disabling all extensions)

@simonbs Check your ping times. Sonoma on my Intel Mac had networking issues which (among other things) led to pages not loading. I had to eventually downgrade to Ventura and now it works fine.

The main symptom was ping times spiking to hundreds of milliseconds and timing out, getting worse as uptime increased.
