Hello,

As of today, the SCB cluster consists of 4 machines in each DC, which spreads the load more evenly and allows for better handling of bad situations. Kudos to Alex who carried out the work of re-purposing the ex-SCA nodes (by previously moving Zotero to VMs)~[1]. The deploy repositories of SCB services have been updated~[2], so you don't have to adapt to the new situation - just deploy as normal, but see your service deployed to 8 instead of 4 nodes total :)


Cheers,
Marko
