Some time in between 10 p.m. on February 5th 2014, and 6 a.m. the next day, a number of Simba Hosting services will be being physically moved to a new datacentre.
There is nothing you need to do to be ready for this; just to be aware that during that time, if/when you find your website or email to be unavailable, then it is expected. Please wait until 6 a.m. on February 6th before raising any support requests!
