Lahat ng ISPs may minor issues talaga. Expect mo yung random service interruptions, pero if well maintained ni Converge yung Fiber lines sa area mo, there should be little to no disruptions.
Just a note. Sometimes, yung speed goes down on peak hours. Though since Fiber yan, it shouldn't go down that much.
Yung sa PLDT namin, if 8pm na, yung latency or ping is always spiking. Same 1gbit speed parin at peak hours pero yung ping goes from 8ms to 14ms at peak hours. Not that noticeable pero I can confirm na hindi ito nadala sa margin of error.
