I feel like it's safe to assume the official Internet Archive would not write a "friendly"/attempt-at-humurous/unprofessional/confusing/delivered-by-popup message advertising a devastating security breach. Oh also while announcing that nowhere else.
Obv an attackers ability to insert a message does imply a breach beyond a DoS. But I am pretty confident that message was not from the IA.
Verge reports someone has taken credit for an ongoing DDOS against IA.
"An account on X called SN_Blackmeta said it was behind the attack and implied that another attack was planned for tomorrow"

That class of sites generally is, yes. But on HN we go by article quality, not site quality (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...) and I didn't see a better specific article on this. If there is a better one, we can change the link again.
