7 of 10 FTSE 100 firms unprepared for the next major DNS attack

Are You Built‑to‑Last or Bare‑Bones?

Alert! ThousandEyes’ latest DNS performance study shows that 72 % of FTSE 100 firms aren’t ready for the next big DNS attack. It’s the same kind of arm‑cracking failure that hit Dyn in 2016.

What the Numbers Say

  • FTSE 100: 72 % not properly hardened
  • Fortune 500 (top 50): 68 % vulnerable
  • SaaS leaders (top 25): 44 % exposed

DNS is basically the Internet’s phone book. Your domain name www.yourcompany.com gets turned into an IP address that your customers use to find you online. If that phone book crashes, the whole party gets lost.

Why It Matters for Business

Sources like 451 Research say that “digital experience is king.” If your DNS isn’t beefed up, the store shutters before anyone can make a purchase. This is no longer a technical nicety—it’s a commercial survival tactic.

You might think a simple DNS glitch is harmless, but it can hinge your brand’s success. Proper architecture choices, stubbornly sticking to best practices, and testing across regions can turn a potential disaster into a resounding defense.
