Hello again,

As a follow-up to my last note on the September 6th DDoS attack, we wanted
to provide you with an update. There have been no further attacks in the
last week and our sites are now running normally. Our SRE team is
continuing to monitor the situation.

Based on what we learned in this attack, our security and engineering teams
are researching and putting together plans for more protection of our
infrastructure to address any potential attacks in the future.

We appreciate everyone’s support, particularly the folks on the SRE team,
in helping to restore access.
