All of them have their own databases for each region that contain the data of the characters who play on them d2r items for sale. This is because there are way too many players playing Diablo 2 to just continually upload all the data of everyone's to a only one central point.
"Most activities in games are performed against this regional database because it's quicker, and your characters are 'locked' in the database so that the individual character record integrity. Global databases also have backups in the event that the primary database fails. fails,"These regional databases are periodically able to send information back to the central database which means that Blizzard has one record (with backups) of your thicc level Barbarians, Necromancers, and so on. It's all good--until that central database gets overwhelmed and the entire system, much like the people working on it, needs a nap.
"On Sat. morning Pacific times, the servers experienced an outage across the globe due to an abrupt and significant increase in traffic. It was a threshold which our servers have never been through before, even before launch," Blizzard explained.
This was caused by an update that we'd launched earlier that day with the intention to enhance performance around game creation-these two factors combined overloaded our database across the globe, causing it to go out of service. We chose to roll back the Friday update that we'd previously released hoping to ease the load on servers over the course of Sunday, while providing us with the opportunity to look into the root of the issue.
On Sunday, though it became clear that what we'd completed on Saturday wasn't enough. We noticed a larger volume of traffic, which caused us to experience another interruption. Our game servers were observing the database's absence and then attempted to reconnect frequently Diablo 2 Resurrected Items, meaning the database could not be able to catch up on our work due to the fact that it was dealing with a constant stream of connection attempts by game servers.
