After more than two weeks on the market and over a dozen issues being reported even before launch, the PlayStation 4 is still going through some serious growing pains. The biggest issue that still remains is the uncertainty and instability of the PlayStation Network, Sony's online gaming platform. Without mentioning any new server upgrades to handle the heavy influx of gamers coming on to the network after the E3 presentation battle, Sony's has now shut down part of the system in order to handle server loads.
If you want to redeem any PlayStation promotional codes or PSN Card codes, you won't be able to for the foreseeable future. Aside from the PS4 just sitting there at the Redeem Code screen after number entry, a blog post appeared on the PlayStation Blog about the service interruption. Social Media Manager Sid Shuman wrote,
We are aware that users are experiencing some disruption to the PSN service. To minimize the inconvenience we have suspended the "redeem voucher" functionality while we investigate further. Unfortunately this means that money cards, product vouchers, PlayStation Plus vouchers, PS3-PS4 upgrade vouchers and any other vouchers for digital content are not redeemable at this time. Other PSN features such as log in, online multiplayer gaming, PlayStation Plus trials, PlayStation Store (excluding voucher redemption), Trophies, messages, friends, etc. are all available.
We apologize for the inconvenience and will provide an update soon.
There's also a thread that has been updated a few times since the announcement, with no real answer in sight as to when the service will be brought back up. Sony says that it still does "not have an estimate on when the system will be available at this time" and to "please try again later this evening or tomorrow."
In trying since the post, I've still not seen any successful redemption of a promo code. Now, I know this may not seem like a big deal to most people, however, it speaks a lot to the stability of the network as a whole. Gamers are still reporting complete meltdowns of the PSN service, including dropped lobbies, lagging out of games in-match and trophies not saving or being lost. So while the Redeem Code screen might not be something you use, it's the place Sony is working on a stop-gap to try and fix other problems at the same time. For now, PS4 users will still have network latency issues and will have to deal with it until Sony fixes the problems.
