Found HV cable for VIP1L231 to have extensive rad damage and kept failing after re-termination.
Tomorrow I will route a spare HV cable to VIP1L231 and hope it is good.
Finished HV re-terminations for VIP1L232 thru VIP1L236 and VCG1L23, all showing good readbacks.
Will finish VIP1L231, VIP1L237 and VIP1L238 tomorrow.

COMMENT ON Apply Emergency PHP update to web servers
The maintainer of the REMI repo we use did not get advance access to the updates before the 10AM embargo ended and had to build the packages and push them out late this morning (https://github.com/remicollet/remirepo/issues/355) . As of right now his primary repo is overloaded and the update has not showed up in the various mirrors around the globe. We are still trying to get the package updates downloaded in order to be able to install them.
