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.

Although it had some nice features, I wasn’t given a ‘root’ (or super user) account and (as I sometimes do) was able to completely trash the instance within a few hours of creating it (I tried to manipulate the permissions on the master database user and ended up revoking all of them).

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.


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.
