Edge protections went live hours before disclosure: Cloudflare at 03:02 UTC; Imperva, Akamai and Fastly on 21 October; Fortinet signatures by 22 October

Every vendor says the same two things: it is a stopgap, and patch anyway.

Fact-check

A2 Reported status overstated · Event · verdict: holds in part · the status word overstates the evidence

Only Cloudflare gives a pre-disclosure go-live time (03:02 UTC on 21 Oct, its own account). Imperva says it verified protection and monitored before the announcement but gives no time; Akamai and Fastly give only a 21 October post date; Fortinet's article is dated 22 October 07:55, after disclosure, so 'went live hours before disclosure' does not cover it. Each date is the vendor's own word, A2; 'confirmed' overstates.
