Nasdaq (NDAQ) says that all earlier intermittent gapping has since been resolved; all systems are operating normally

Exchange notices of this kind follow a well-worn sequence: an initial report of intermittent quote or order issues, a resolution notice, and then the post-mortem. The resolution language here, all systems operating normally, is the standard closing statement and historically marks the point where the event shifts from an operational story to a question of scope. What matters after the fact is what the gapping touched: whether it was confined to the consolidated feed and display layers or extended to matching and order entry, since the former is typically cosmetic while the latter raises questions about order handling, busts, and clearly erroneous trade reviews. Episodes of brief intermittent disruption at major US venues have tended to pass without lasting structural consequence, but the follow-ons are the exchange's own incident summary, any regulator comment, and whether affected participants flag execution issues. The distinction worth drawing is between a venue-specific glitch and anything that touches the SIP, since the latter widens the blast radius across all listed trading rather than one operator's book. Absent further detail, the operative fact is that normal operation has been restored.
