I don't have much technical background, but wanted to share somewhere that... last month, some news apps on my Android 13 phone stopped loading; most importantly, Germany's Deutsche Welle, but also another public broadcasters'apps from Germany, and to a lesser degree the British BBC. I live and I'm from the country south of the border of the US, and my ISP used to be the dominant one (not anymore).
Checked if the apps would run fine on my phone's network, not the landline ISP. They did. They also ran smooth with a VPN, an integrated proxy, and finally, with another ISP, after I cancelled with the previous one. So, I guess it may have been the dominant ISP. Other news apps and anything else ran fine.
Are you used to these things happening every once in a while and I shouldn't make a big deal of it?
Best wishes
