Fast-forwarding six days, to the next Log entries under the rubric of June…

|---|---|---|
| 06/10 | 06/19 | Two GRU edges OOM |
| 06/11 | 06/21 | ORD transit loss destabilized Managed Postgres clusters |
| 06/11 | 06/21 | Everyone lives on NULL island (Depot, WG placement) |
| 06/12 | 06/21 | Elevated Sprites error rates in SIN |
Apparently, the first was due to an accumulation of pending metrics (waiting for export from those edge nodes).
(And this sunburst overall, 
, was very welcome insight into all four incidents, of course.)
Aside: A recent commit to the official docs repository introduced explicit bounds on metrics, including a limit on the size of your app’s /metrics response, which people had expressed doubts about before.
(Metrics and logs have generally been getting overhauled and having their expectations clarified lately.)
