implying they were even in the office at all.. pretty sure they have been work from home for the past month and a half. Depends, if a server went completely dead, hard to replace that from home. If some hardware adjustment were needed or a back up tape needed to get changed, hard to do that from home. Because everything is like in the cloud nowadays, doesn't mean you can do just anything from a console at home. ;) I suppose all their server are virtual machines, so could be done remotely. Maybe the time is needed to check consistency and identify what caused the rollback Virtual machines still run on actual hardware somewhere :) Especially when you need to store nearly a decade's worth of game data for an MMO as large as this one but they can be move easily to another host :) at least I hope they have HA enabled :)Those are just assumptions, maybe there is an entire node down, maybe there is not enough ram available to run more hosts, in these situations you want someone in the datacentre locally anyway. All modern 24/7 data centres have a 24/7 local team exactly for these things. The dev team that are not needed inside the datacentre can work from home true, but is is not just about one code fixing some guide and everything is ready to go. This is a large team effort going on. We have to wait on answers from Arenanet, now its just pure speculation.
