AWS also recently ended support for Mysql 5, so if you had an RDS instance with that version running past the cutoff, your support costs ballooned exorbitantly.

Yup this one hit me hard. USE2-ExtendedSupport:Yr1-Yr2:MySQL5.7 sent my bill up 70%.

How long was it before the notice and you getting charged extra?

[noctarius]

Seems like I'm a lucky one. Neither using RDS nor MySQL. But seriously, ouch. I mean, I get why they want people to migrate to supported versions but ...

I wish we could implement this internally via chargebacks. The teams that refuse to upgrade their stuff should be forced to pay for the externalities they cause.
