Re: AWS hosted sites like slack unreachable

Margi,

I ran into that years ago with AWS.  I had a service provider clearing 
calls for me, and they were hosted on AWS.   Kept pushing my service 
provider to open tickets with AWS. The issue would resolve for a day, 
then return, etc.....  There was no permanent resolution offered by 
AWS.  The issue kept re-emerging.  I wasn't a paying customer of AWS, so 
I had to find another solution.

The solution that I was forced to use was to set up a proxy on another 
network.  I built a virtual server (I used DigitalOcean), set it up to 
proxy that specific traffic, and I had to bounce all the traffic off of 
that proxy to get in/out of AWS.

Keep that solution in your back pocket if you don't get this cleared up.

Good Luck,


Pete
