Are People Working from Home?
The snow has ground the country to a halt, but that doesn't mean that everyone is having a day off. For a lot of people now, me included, being at home means that they can still do a day's work. Many businesses now have VPNs which allow their employees to work remotely and consequently many people are taking advantage of that rather than venturing out. The two graphs below show the amount of VPN traffic we were seeing the week before Christmas compared against what we've seen so far this week. VPN traffic this morning was up about 40% compared with 2 weeks ago. 
Question is though are some people that could be working from home out making snowmen? Dave Tomlinson Plusnet Network Transformation
