There is no guarantee that this issue won't occur, it sounds like your area is over subscribed and during peak hours, which due to covid is currently all day, you'll notice that your connection will degrade due to there being too many people online, over subscription can be fixed but it takes an investment and resources, currently resources aren't going to be available to perform an upgrade, you could try switching to an ADSL provider, as they provide lower speeds they generally don't suffer as much from over subscription, but as mentioned the trade-off there will be slower speeds, you would have slightly lower latency but its not likely to be massive enough that the majority of people would even notice, considering we are talking literally thousandths of a second here
