Ping scales by Champions

Just had a match. Nothing notable at the start.

But as soon as I got enemies in my screen, about 1000 units away, ping skyrocketed from 40 to 600. And as I got ganked, the game almost disconnected me until they got away. I would call this fucking bad luck, but it repeated FOUR TIMES IN ROW. FOUR.

So the game makes me look perfectly normal and responsive all the time except when I actually need to be. I disconnected so I could not inflict any further feeding but I guess I get 4+ reports from this total image they got.

Now that the system has ripped my anus, what can I do? Can I trust this game's servers? I have never had any problems like this before, and other games played fine as I now tried them.
