So are they updating their capacity or was this a run?
I’m sure they are frantically growing their capacity. This is what every startup dreams of and I’m sure they architected it correctly from the beginning for high growth rates. Lots of companies use “elastic” cloud services to quickly grow their capacity. Unfortunately, Amazon has a huge market share in such services.
A test run? Maybe, but I’d lean toward unexpected surge in growth all coming from ex tweeters.
