Please correct me if I’m wrong, but If the “internet goes down”, it’s most likely the fault of DNS tables. No ISP would willingly just shut down their servers. So, how do you prepare for something like this?? Write down the direct address to your most important sites, that way you bypass DNS. Or download your own DNS table that why you don’t have to rely on the DNS servers or DNS tables.
In terminal or cmd.exe, use: NSLookup website.com
Log all your most important website IP’s and keep them somewhere
GAW: IP: 104.21.71.144 IP: 172.67.145.123
EDIT: I believe it’s way more complicated on a non- dot com site. Testing now. I believe you may have to create a custom DNS route/translation or have your own table
2ND EDIT: IMPORTANT! GAW is behind CloudFlair, a DDOS Security type firewall. While this may work for other small websites, it’s likely not going to work on GAW because the IPs above are owned by cloud flare and are then, internally within cloudflare, translated to a secure address. Unless an exception within cloudflare is added, you will likely be unable to access the site using an IP.
Others, smaller websites, would work if you had the IP
if the records are deleted from the root zones, then you get this when looking for facebook.com:
** server can't find facebook.com: SERVFAIL
No such thing as 'downloading the database', I'm afraid.
