Загадка по хостингу

[Mishelka]

все оказалось куда сложнее. замена режима TCP Congnestion Algoritm просто совпала по времени со стабильной работой Vega.

вчера ближе к 17 часам PPPoE начал безбожно падать. как показал лог роутера где-то после 22 "падения прекратились" и с утра вроде все работало.
но настала сегодня час "Ч" и приколы повторились:
