If you traceroute 149.112.112.112 vs 9.9.9.9 is there a difference?
Finally able to reproduce the symptoms reported. The routes seems to diverge at 10.247.89.65
Routine speed testing showed I was on a slow mast yesterday evening so I rebooted just the modem and the issue was seen on an Android 11 mobile and a Samsung Tab 8 tablet.
Currently the issue seems to be limited to
MNC 234
MCC 30
Cell ID: 3668998
eNB ID 14332
which happens to be on a university campus.
