When external connectivity is restored:
- There are no existing connections for TSA1 to handle.
- IPFE-A1 still retains control over TSA1.
- Clients route new connections to TSA1 over time.
- In the interim, there is a substantial imbalance between the two IPFEs as well as between the servers in the two TSAs. The IPFEs monitors the traffic for imbalances and distribute new connections to reduce the imbalance.
