After recent TOR problems due to a mix of electric and provider issues, we activated a permanent backup TOR proxy that can work seamlessly if the main TOR circuit breaks somehow. Is an independent, low energy device connected with a gigabit ethernet to the optical fiber.

More, we also activated a new, modern and more capable UPS to have 30+ minutes of resiliance even in case of electrical disruption (yes, there is a lot of wind here). The backup line is usually activated in 5 minutes so it should be more than enough.
