If I recall the timeline correctly, she was in training during pre-holiday season. But in case we're talking about different things, just FYI, in telco and networking _nothing_ happens after Thanksgiving--it's essentially "quiet" time as customers go into holiday breaks and network freezes.
If you meant Cloudflare customers would make heavy use of their services during holiday season, yes -- but nobody deploys that kind of solution _during_ sales, all online retail pre-plans for that months in advance (cloud resources, inventory, security, etc.), so they wouldn't _buy_ those services then.
