Adjusted the gains for the 60, 120, and 180 Hz suppression. Also moved around the 30 Hz, looking at a few other frequencies as well.

Brought back to 30 Hz for the "floating" value. Kept some gain adjustments, as the suppression at the 60 Hz harmonics looks better by eye than it did.

Rates on NL NDX, IDX/BLM in NE spreader have decreased compared to before B going down for a target change. More tolerable but may still be useful to check orbits.

It was noted that neutron dose rates in 2L23 spiked a little after 0400 this morning (fig 1). Taking 2 MV/m out of 2L22-3 cut the dose by about 5 rem/hr (fig 2).

Problems resolved. Issue was tracked down to a failing fiber converter module (sfp+) on 1 of the redundant links between devmc02sw1 and our core router(acc-vss-1). The link kept going down and then would come back up causing periods of network slowness. Once I physically shut down this link things started to resolve immediately. I will leave this link shutdown for now. We will replace the suspected fiber module. Plan would be to bring the link back up next maintenance day unless we get the approval to bring it back up before then.

Moller folks would like to continue running FFB as long as the hall is okay with it. Seems to have decreased their target position oscillation by a factor of ~6. As with yesterday, not running RF corrections yet, will try ironing that out with the pass change next week.

cavity is tripping on SELQfault as shown in the archiver.
We will add delay to this type of quench at the next opportunity as the quench delay is only for the firmware quench
