Is O2 down right now?
O2 appears to be working normally — report volume is within the typical range for this time of day.
Is O2 down for everyone or just me?
Right now down.now isn't seeing a broad O2 outage, so the problem is most likely local to you — your connection, your device, or the app itself. Try the app on mobile data instead of Wi-Fi, then restart the router. If reports start arriving from other people, this page flips to an outage within minutes.
When was the last O2 outage?
There are no recorded O2 outages on down.now yet. Every incident we detect is kept permanently on this page.
How do I report a O2 problem?
Use the report panel on this page and pick what's not working — it takes one tap and no account. Reports are anonymous, and they feed the live signal on this page immediately.
How does down.now know if O2 is down?
Down.Now watches two crowd signals for O2 — anonymous reports submitted here, and public social-media posts about it — and compares the live volume against what's normal for that hour of the day. A sustained spike above that baseline opens an incident, which is usually visible before an official confirmation. We measure what users report, not O2's servers directly.
