There's a large jump around 445739. I wanted to see the trace. 

1) I click on the relevant data point, and then click "trace". This brings up a dialog about recording a new trace. That's not what I want.

2) I clicked on "buildbot stdio". This repeatedly brings me to a page with no content. I try signing in, no change.

3) After trying (2) several times, I eventually got the page to load [I haven't been able to reproduce this...]. This points me to https://chromium-swarm.appspot.com/user/task/33ea40b2197c9810. This has the log:
"""
INFO:py_utils.cloud_storage:Uploading /b/s/w/itIOURAy/tmpXd_MCA.html to gs://chrome-telemetry-output/trace-file-id_0-2017-01-24_12-04-27-49580.html

"""

4) Navigating to that link gives:
"""

Error 403
"""

5) Downloading the gs file directly and opening it, I don't see any memory-infra nodes.
