Bungie names this code but does not publish the wording it prints on screen, so we quote only the code itself: BUFFALO. Any site showing you an exact message for it has written one.
This one genuinely goes both ways, so the first job is telling which you are looking at.
Bungie has every core Destiny 2 service switched on
Bungie's description names three causes: “This error appears to players who are not signed in with their platform account, or if their platform service is undergoing maintenance. Additionally, this error may appear to console players if their PlayStation Plus or Xbox Live subscription has expired.”
The important part for diagnosis: every one of those is on Sony's or Microsoft's side of the line, not Bungie's. A wave of BUFFALO reports usually means a platform is having trouble, not Destiny.
Bungie publishes word-for-word identical descriptions for BUDGIE, SQUIRREL, VULTURE and STINGRAY. Five codes, one cause, which is why this page covers them together.
Check PSN or Xbox status first, because platform maintenance is one of the three documented causes. If the platform is healthy, check whether your subscription is still active. On PC, check that you are not signed in to Destiny on another machine.
If the problem is platform maintenance rather than Destiny, our scheduled-maintenance page collects announced windows across every operator we track.
Operator documentation: help.bungie.net. Bungie documents its error codes in a public directory of over 300 articles. Those articles describe causes and fixes and never quote the in-game dialog, so neither do we. BUDGIE, SQUIRREL, VULTURE and STINGRAY carry identical text in Bungie's directory.

Start with: Sign back in to your platform account. Not into Destiny — into PlayStation Network or the Xbox network itself. The game cannot do it for you.
