You mean Monday 23rd?  Nothing unusual there.  Currently, the OpenMath wiki
only makes connections to the svn when somebody is logged in whose svn account
I configured in the SWiM database, i.e. one of us, but on that day no such
person was logged in.

How would the Trac be related to the OpenMath server?  We're not able to link
it to the OpenMath svn repository, as that only works on filesystem level if
both Trac and svn are on the same machine.

What I know is that our servers were generally quite unstable this week, as
some hardware maintenance was done and not all systems (e.g. MathWebSearch)
recovered immediately from the reboots.  But I'm not sure if that is related.
