<p>There will be a period of downtime tomorrow (Tuesday) afternoon in order to replace UPS batteries, beginning at 3pm. <br />This will probably involve two short periods of downtime, each about 10 minutes long.<br />Each shutdown will be announced on Milliways and via the society twitter account (<a href="http://twitter.com/sucsexec">@sucsexec</a>)<br />Apologies for the short notice</p>
