I have a UPS designed to run long enough to shutdown my server gracefully. I can manually turn it back on if the outage is extended.

If I was designing a critical service the ups would have enough runtime to switch over to some other power system (solar batteries, generator, second circuit, etc)

Why even have a phone number if it is useless?

• forgotten glasses
• arranging a special event
• deliveries and business coordination
• employees calling out
• etc

University press releases, they often are very far from what the actual research says

Tldr:

• some airlines say power banks must be within arm’s reach
• some airlines say power banks must be stowed away

Check with your airline before traveling.

The key is defense in depth. Don’t trust anything more then you need to. Even if your router is compromised the hosts should be hardened, the traffic should be encrypted, etc
