1. **What was observed:**
   - Initial configuration and verification steps were taken, including setting up a loopback address and advertising a prefix. Connectivity tests to 44.192.100.100 failed with "Network is unreachable."
   - Traceroutes to 44.192.100.100 and 44.192.0.100 both failed, showing issues beyond the first hop to TransitAS.
   - TransitAS confirmed successful ping tests to 44.192.100.100, indicating no issues on their end.

2. **What was decided:**
   - Added a route for the 44.192.0.0/16 prefix via TransitAS to resolve the "Network is unreachable" error.
   - Repeated traceroutes to gather more data and shared results with TransitAS for further investigation.

3. **Why:**
   - Adding the route was necessary to ensure the network had the correct routing information.
   - Repeating traceroutes and sharing results with TransitAS helped identify the issue beyond their network, facilitating coordinated troubleshooting.
