H1 dropped unexpectadly.  StripTools showed oscillations on LS-POP_A_LF and the SRM & PRM a few minutes before the lockloss.  Then Vinny noticed the increase in the EQ band (0.03-0.1Hz).  Then Terramon finally displayed the 5.6 EQ from Russia.  We dropped out before the R-wave estimate, but fairly certain the EQ is what knocked us out (and also knocked L1 down 3min after us).
