Field notes
- Atlanta 2600 moves to Sandbox, 483 Moreland Ave NE, from its October 2, 2026 meeting (per atl2600.org). The 2600.com list and the Meetup event pages still give Lenox Square Mall; the group's own site wins.
- The Atlanta LockSport meeting on October 3, 2026 is cancelled because members run the Lockpick Village at BSides Atlanta that day; meetings resume November 7, 2026.
- BlackHack Society cancelled its July and August 2026 regular sessions; check the Meetup page before going.
- The ISC2 Atlanta website (atl-isc2.org) showed a hosting suspension page on September 24, 2026. The chapter's most recent meeting was on the SecureWorld Atlanta agenda.
- DC470 (Alpharetta) closed in mid-2026. ACE678 (Marietta) meets on the second Wednesday at the Marietta Burger Bar, but says plans occasionally change; check its Discord before going.
