overload on gnt-fsn cluster
Higher than usual traffic was observed starting 2022-12-16 06:35UTC on the two onionoo frontends which negatively impacted other services (gitlab-02, eugeni, so mails, and anecdotal reports of failures of static site deployments).
Situation has returned to almost normal at around 16:00, enough to be able to open this issue. @hiro will followup with Microsoft to see if this was some legitimate traffic or an attack. It's possible a researcher was fetching data from the frontends possibly a little too enthusiastically.
