High load isn't necessarily an emergency, but it may be a heads-up before a site noticeably slows down. Sometimes there are weird spikes that just go away, but sometimes this is an indication of a Denial of Service.
At 12:27pm, our alerts started firing. Multiple ones -- website down, server down, secondary monitoring -- one of our client's servers had completely disappeared off the Internet.
No, you should not. You should let us worry about them, and go back to your business.
Seriously, we're getting questions from all kinds of people about whether this matters. I'm a bit surprised that there is any question about that. Would you be concerned if your top salesperson was selling for somebody else? If your cashiers were jotting down credit card numbers when they charged a card?

This all sounds dreadfully scary. And it is... but don't panic! Instead, read on to learn how this might affect you, your website, and what you can do to prevent bad things from getting worse.
The only thing the homeowner may notice is a slight slowdown in their Internet connection. But meanwhile, their cable modem or webcam was out bringing down the Internet. This was just one of the scenarios described by David Hobbs at the MIT Enterprise Forum.
This is why you want to be on our maintenance plans. Our number one priority is recoverability, from just about any risk. And today, we had a client that needed this, in a very bad way!
A past customer just called, with email trouble... suddenly their email had stopped delivering. This customer had been acquired by another company, and we had shut off their web hosting service months ago, as their website had been retired.
