RunningMan:shawnybear: [snip] both phones being Android and doing cloud backups. still have no clue as to what could be saturating the upstream to cause my whole internet to just stop working for upto 5 minutesThere's the clue right there.

Same applies to cloud backup on desktops.
If I had to blame it on something it would be cloud backups.
