This will affect mostly only users in the Oceania region.
Due to backend performance issues (asset retrieval from search & load), we are temporarily taking the Materia Oceania region hosted in Singapore offline from November 13th. There is a plan to bring the region back online early next year with these performance issues addressed.
Depending on networking, users that typically use the Singapore server will be routed to the US or Europe. You might notice an increase in latency, please keep an eye on how the service feels and report any issues you find.
For Materia and Live Component users in other regions, this should in theory not affect you, the servers will scale to accommodate the extra users.
