Update: April Fool's!
Linden Lab just announced there's a glitch in the PBR (Physical Based Rendering) code that affects mirrors in Second Life. Part of the glitch is that bumping into mirrors, touching them with an object, or dropping a mirror onto the ground can result in them breaking.
And when the mirrors break, the person who caused it will go through a number of glitches, such as trouble rezzing, teleporting failures, crashing at sim crossings, difficulties in shopping at Marketplace, and more, for a period of several days.
Supposedly for most involved, the period of time is seven days. Then the issues all clear up.
