A switch warning, a spacewalk, and AI agents that sleep.
Zyxel’s Patch 3 warning
First, check the build number on your network switch. NHS England issued a November fifth alert for Zyxel’s GS1900 series after researchers found that an earlier fix left a separate vulnerability open. The issue is in the switch’s web management interface. Zyxel says someone who can reach it from the local network may be able to run commands without signing in. The vendor lists Patch Three for ten affected models. Match the download to your exact model, then verify the firmware that is actually running after the reboot. Limit who can reach the management interface. If you suspect someone already got in, preserve the logs and investigate separately. The update cannot tell you what happened before it was installed.
The last roll-out solar array
In orbit, astronauts installed and unfurled the eighth and final roll-out solar array on the International Space Station on November fifth. NASA says the combined upgrade raises the station’s generating capacity from one hundred and sixty to about two hundred and fifteen kilowatts. The older arrays still contribute wherever the new panels leave them exposed to sunlight. That gives operators more room to power experiments and station equipment. Batteries carry loads in darkness. NASA’s completion report gives a capacity figure, with no measurement of output over a full orbit.
What happens when an AI agent pauses
And Google says Agent Substrate one point zero is generally available on Google Kubernetes Engine. The runtime is designed for agents that work in bursts and spend time waiting. It saves a paused session’s memory and files to storage, so another session can use the worker. When the agent is needed again, it can resume on an available worker. Open network connections do not survive a pause. Before a production rollout, test whether your agent reconnects and can tell if an earlier write succeeded. Google’s headline performance figures still need testing on your own workload.
