At present, there's a number of options for short-term solutions as well as plans to overhaul Diablo 2's design so that it's more scalable for D2R Ladder Items modern demand.

The developers are also planning to introduce one-time login queues, like World of Warcraft, to prevent situations where the servers get overloaded when hundreds of thousands of game instances are launched at once:

To help with this to address this, we've put people in a login queue similar to what you encountered when playing World of Warcraft. The goal is to keep the players at a safe level, which is what we have at the time which allows us to track the areas of the system that are straining and address it before it brings the game to a complete stop.

Each time we fix an issue, we'll be capable of increasing the number of caps. This login queue has already been implemented in part in the backend (right now, it looks like a failed login in this client) and is expected to be fully launched in the near future on PCs, with console to follow after.

Also, players will be restricted, but only for the instances of games being made, closed, and then recreated within short periods of time This is usually the case where players are farming out areas such as Shenk & Eldritch or Pindleskin.

It's just an indication that you are being rated limited to D2R Items for sale help reduce the load temporarily on the database so as to keep the game running." Blizzard advised.
