What security settings would randomly and only intermittently block UDP data to a server? It really makes no sense at all. The worlds shittiest DPI DDoS protection? No, that wouldn't be a "server setting". Bad iptables setup? No, would be consistant.

I really hope they release details, because technically it doesn't make any sense at all. They keep talking about "checking the logs" for packet loss, but neither client nor server logs packet loss in any consistant manner. Maybe the faceit client? In any case, if both flashpoint and NIP insist on taking the public PR route, they should release the data, but they probably wont because it doesn't make sense.
