Ouch!

Those times are not cumulatively added, instead in the trace above,
google is 264ms away.
Still, that's *really* slow for a destination in the SF Bay Area from
Noisebridge. Your first clue should be that the first hop past our DSL
circuit (75.101.62.1 in the trace above) is reporting 515ms. That
should be more like 1 - 5 ms.
That would suggest to me that the Sonic.net uplink is super congested
and your traffic is "waiting in line" on the upstream interface
transmit queue.

By seeing sonic.net as your path out via Bikeshed, that would suggest
to me that the monkeybrains circuit isn't setup or being used.
Normally (whatever that means, these days.... I mean how it was
originally designed), egress traffic should be going out Monkeybrains
for early everything.
