Infrastructure and system health only. Numbers shown (such as reporting tractors) reflect software infrastructure signals, not business metrics.
What a status word is made of · each service card shows up to three signals. Reachable is checked from outside, the way a visitor arrives (address, certificate, network path, server). Errors is the share of real user requests that failed in the last few minutes, from the servers' own counters; above 2% the card reads Elevated errors even if the site is reachable. Response is how long the service took to answer our check, timed from our own servers in the cloud, so a person on a mobile network will usually wait a little longer than the number shown; above 3 seconds the card reads Slow. Pipeline rows show their own measurements instead: positions flowing per minute, backlog waiting to be processed, and how long ago the last activity summary was produced. A dashed grey chip means that signal is not measured yet for that service, so its status is based on fewer signals than the others. Down means unreachable or not answering at all.
overnight — minimal field impact · the disruption fell mostly (70% or more) inside the overnight window, which is defined in UTC: it starts at 19:00 UTC and ends at 03:00 UTC. In local time that is 22:00–06:00 EAT (Kenya · Ethiopia · Uganda) · 21:00–05:00 CAT (Rwanda) · 20:00–04:00 WAT (Nigeria). Anything up to 18:59 UTC counts as daytime.
during daytime / peak hours · 70% or more of the disruption happened outside that overnight window, when tractors are working — these are the incidents users actually feel.
spread across day and night · the disruption straddled both windows.
On the daily bars, Degraded means the service missed its target for up to 10 minutes that day (99.31–99.9% uptime); Partial outage means 10 minutes to ~1 hour 12 minutes (95–99.31%); Major outage means more than that (below 95%). The severity reflects how long the day was disrupted, not how badly at any moment. Percentages are the share of each day (sampled every 5 minutes) the service met its target — they are never adjusted for time of day. The live status word next to each row (Operational / Degraded / Outage) describes right now, from live probes.
