The developer of Playerunknown's Battlegrounds PUBG Corp has apologised for some issues within the battle royale title.

In a post on the game's Steam page, the firm says that it has been experimenting with new solutions to prevent distributed denial-of-service (DDoS) attacks, which have been ramping up over time. PUBG Corp says that November 2019 and February 2020 were particularly bad for these.

The new countermeasures have resulted in poor performance and connectivity for Playerunknown's Battlegrounds, apparently. The newly-developed defenses have reduced DDoS attacks by around 85 per cent, PUBG Corp claims.

"Our dev team has been increasing our DDoS defense solutions, working with various server infrastructure providers and analysing their effectiveness in order to protect our game servers and provide a more stable service. At the same time, we're working on our own defense system specifically designed to protect PUBG's game servers," the company wrote.

"While testing various DDoS defense solutions from external infrastructure providers, server locations were often located far away from standard locations, which resulted in increased ping and other network issues for some players. Additionally, many players have suffered constant packet loss issues due to the experimental DDoS defense solutions deployed by these providers. We know that we could have been much more open in communicating these reasons with you, but did not want to contaminate tests and results by letting the attackers know we were doing this testing. Regardless, our sincere apologies to players who experienced ongoing connectivity issues during this time."
