Lightsail Network Isolation

Amazon Lightsail started offering a managed database service a few months ago.

I took a look at it … and tried it out … a while back and wasn’t really happy with it.

How to make Steve shriek

My friend Steve showed me this picture today … at first I thought it was simply a ugly phone wiring job that he found at clients site.

Wiring

Turns out it’s actually an ETHERNET connection … that’s currently carrying a gigabit signal. Apparently it’s been working fine for the past 5 years.

When Steve saw it … he shrieked out loud.

Suffice it to say, Steve is going to replace that ‘connection’ with proper CAT6 next week.
