Ddos attack in ranked HS

Its been happening far too often, i get my opponet down to less than 5 or bust out a 8 hit combo, my HS buggs out and i lose my game, I normally wouldnt care, but im closer to legendary in wirl than I ever been, and im tired of the cheating

DDOS stands for Distributed Denail of Service. Since there’s only ever a maximum of 3 connections (player, server, battle.net), it can’t be a DDOS Attack.

More than likely you disconnected. See the relevant stick for more info.

DDOS stands for Distributed Denial of Service. Since there’s only ever a maximum of 3 connections (player, server, battle.net), it can’t be a DDOS Attack.

A DDOS attack is usually performed by a huge number of (connected) devices trying to get a website or a server unable to reply to the network packets.

Blizzard seems to be hosted behind Akamai services (Akamai Site Shield is one of the best Network Solution in the world). If a DDOS attack occurs against Blizzard, let say specifically against the Hearthstone Servers, Akamai will mitigate the attack and drop the undesired packets (based on filters, such as headers) before getting into the Blizzard’s network. But the filters add an extra network layer before hitting the Hearthstone servers.

Akamai is using multiple edges located worldwide to provide a better experience to the end-user. Unfortunately, a DDOS attack against hearthstone servers from the same “edge location” as a player may generate some latencies, more likely for someone playing far away to the server location (such as South American player playing on Europe servers) and the closest Akamai Edge is mitigating a DDOS attack.

Furthermore, as most of the online games, Hearthstone is using the UDP network protocol to transmit the packets. This protocol is faster than TCP protocol but not reliable as there is no acknowledgment of packets. So packets may be lost and the destination will never receive it.

So as many other games, DDOS attacks may affect players’ gaming experiences, but thanks to the Akamai infrastructure (or other Network Providers) it should limit the number of affected users.

I hope I made it more understandable.
