Dear Friends and clients of Jack Russell,
Did you lose your internet service or access to an important website this past Friday? You weren’t alone. Although it sounds like something out of a James Bond movie, a foreign government attacked a multitude of DNS servers and was able to take down a big chunk of the internet. They did this by co-opting tens of millions of online devices, everything from baby monitors to Nest thermostats, and directing those devices to send data to very specific locations. This was a very sophisticated attack that likely took months to plan and therefore hardly the work of your typical hacker. Big online sites such as AirBnb, Twitter, Spotify, Woo Commerce, Shopify, etc, were all brought down, some for a few minutes, others for a few hours. So what does this mean to you and how can you take precautions?
First of all, here’s how this happened. Websites have unique online addresses based on a numerical value. These are the IP (internet protocol) addresses. My site, chefjohnmalik, can actually be found at 18.104.22.168
A DNS server translates that numerical value into the web address of chefjohnmalik.com. When the websites started going down it was because the DNS servers (not the actual websites) were taken offline.
The downside is that this will probably (definitely) happen again but who knows when? So please think about this. If you did lose your internet for a day or so, how would your business survive? What could you do today to prepare you for the next outage? What systems could you backup to a local hard drive (not cloud based) that you could still access even if your internet went down?
If you’re one of my restaurant clients, how could you prepare yourself if Open Table went down on a Friday night? Perhaps you can make a paper copy of the night’s reservations on a daily basis?
If you’re in health care or medical, could you do the same thing with your appointments? Is your POS system online and if so, what could you do if it went down? How would you make a sale?
Now when this does happen again, you might want to try accessing a particular site directly via its numerical value, all you’ll need to do is find it.
If you’re running Windows, just hit the start button, type in “command prompt” and a black box will open
Type in “tracert” then the web address
A search for my IP address would look like this—> tracert www.chefjohnmalik.com
The IP address is what comes up next to where it says tracing route to chefjohnmalik.com
Here’s a screen shot of my own IP address.
So my suggestion is to spend 30 minutes or so finding the IP addresses of your important sites, save those addresses somewhere safe, then if the same thing happens, you can try typing in the IP address which bypasses the DNS servers and perhaps you can still access your most important sites.
