I worked for a Company that was a vendor for Lenovo. They had some sort of "News about Lenovo" app on all of their commercial grade machines. The content and translations were managed in our system and each computer would pull down the feed from our servers. It was decent traffic, but nothing crazy... Until they made a change and all of the sudden every machine was pulling every hour at zero minutes and zero seconds. We had one minute of DDoS every day at noon for about a week until that was mitigated.

Hopefully no one is using lambda for connection health checks. An empty static page on a CDN is probably a better use of resources.

But yeah, at that point just ping google since they’ve spent millions on availability.

Let's see: ping packet size is say 64 bytes so 128B both ways

My $3 VPS has 1TiB/mo bandwidth limit. So that's 2^40 / 128 / 24 / 60 / 30 = ~200k ovens pinging once every minute (which is ridiculous frequency) for $3

I guess if manufacturer can't afford $3 per 200k ovens sold, he should go out of business or stop stuffing ovens with IoT shit. :)
