I would at least save to your hard drive, an external drive, or a flash memory stick. Do that, and it matters not whether the Internet goes down because you still have the material ready to print or view as you can. If your computer dies, you can still access the files through another one. Download the files onto your computer while you still can.
I see primarily a total failure in the dollar. Whatever you have in your bank account will either be confiscated by the banks or become toilet paper. Your silver and gold in those bank vaults is also subject to confiscation by the banks, so you are better off storing it at home or in a secure location. Whatever risk of burglary is lower than a certainty of getting it confiscated by the banks. Yes, this will disrupt things as people do not show up for work. Yes, expect widespread Internet disruptions, rolling blackouts, and infrastructure disruption. As for rampant crime, whoever tries hitting innocent people is liable to be mobbed by other innocent people because no one wants to be attacked next.
The stock market is not safe, either. Whether it nominally crashes or not, the value will be zero. You are best off using the remainder of the time before Neptune reaches 9 Pisces buying silver (and gold, but since silver is more undervalued, it is your best bet). The weekend of April 17/18 of this year is when it first reaches 9 Pisces, and whatever time you have beyond that point is a bonus. Yes, I would regard it as a hobby as well as protecting your wealth. If you have a sizable base stack of silver rounds, you might wish to get several rolls of silver dimes and quarters, then the older Mercury or Barber dimes and Standing Liberty or Barber quarters. Silver halves are also good stacking, as are silver dollars. Bear in mind that older dimes and quarters are in more worn condition and contain less silver than those 1964 quarters in XF or AU condition. If you haven't yet started, one ounce rounds or late date silver dimes and quarters are your best bets.
