It's dark, but I kindof love situations like this (although luckily I haven't had something like this happen to me in digital space since I was a teenager). Some places I would look: 1) Are you SURE that everything is actually gone? Is there a logfile, a billing trail, sent emails trail from your email provider, something like that? If it was me I'd be looking for a secondary system (like alerts, logfiles, billing, etc.) that had some of this information stored in it as secondary function, and writing some scripts to parse those things and start rebuilding what can be rebuilt. 2) You said you lost all the emails and SMS of your team. Do you have an HR department? Surely they have this information. Your team is likely going to start trying to send emails to each other about this. Can you dump logs off of your mail server to rebuild at least the naming schema? For phone numbers: can you try an old school phone tree style? Start with somebody you know, and ask them for everybody that THEY know and so on. 3) Was there a staging environment that might have had some of the data you're missing on it? 4) Are you really really sure that everything was wiped out? Is it possible that your ERP system is broken (lost its DB connection or something?) and that caused a cascading failure that makes it LOOK like everything is gone? 5) Can you get at the BIND server somehow? Are there logfiles there? I'd love to know more specifics about what "wiped out" means in this case. It seems unlikely that it's properly "wiped out" unless something malicious happened, and even then I think you could rebuild a lot of this from sortof "secondary" data. Think like a hacker, but your system is your own target. How can you steal the data you're looking for from places it isn't really "supposed" to be?
