SgShop.com.sg is down for 'upgrading'

Sgshop.com.sg has been down since yesterday. According to an email sent by SgShop.com.sg to its customers, it will be down for 2 days (yesterday and today, or today and tomorrow?) for 'upgrading'. Please do not panic. Their company has not shut down (I hope). I just ordered a guqin through this Taobao agent. ha. ha. ha. *nervous laughter*

[Latest update (Wednesday 24 April 2013): www.sgshop.com.sg is now back in business online again. Yay]
