All AIDA operations are controlled from the Dell T410 Workstation aidas1 using web browsers.
AIDA has multiple, independent data acquisition servers connected by an Ethernet network.

Mon Mar 9 12:47:18 2020, NH, Report: Unusual AIDA Timestamp Error
|
Noted using my AIDA event builder code, a timewarp was reported and I noticed the ADC event had a different timestamp LSB to the "WR" markers preceding
it, which I didn't think was possible in the merger as it stands

Mon Feb 17 09:48:34 2020, NH, Report: aida09 Kernel Panic & Lost WR
|
aida09 crashed over the weekend and automatically rebooted.
After the reboot the WR timestamp sent to the merger is in the future and hence incorrect

Electricians changed the grounding for the DESPEC platform to a large pillar that goes deep into soil
Change in grounding was apparently successful at reducing the noise complaints in Cave C (R3B)
