Community Fibre Down? Community Fibre Network Status in Real Time
Status computed from public network signals (BGP and active probes) on Community Fibre's infrastructure, updated every ~10 minutes. This is not an official Community Fibre channel.
Is Community Fibre down right now? A red indicator below points to a probable fault on Community Fibre's own London network; if it is green but your own flat is offline, the problem is much more likely to be your ONT, the router or the cable in your building. To check in under a minute: read the live status below, compare it with user reports on Downdetector, and run a speed test on your phone over 4G/5G with Wi-Fi off.

Network trend over the last 24 hours
The chart shows the network signal level (BGP reachability and active probes) relative to the median of the last 24 hours: full bars = normal, low bars = possible outage.
What to do if Community Fibre is down
Community Fibre is a pure full-fibre provider: every connection is FTTP on its own network across London, with no copper and no mobile arm to complicate things. That makes diagnosis simple. Read the badge above first — if it shows a network fault, the repair is Community Fibre's job and waiting is the sensible move.
If the badge is green, start at the ONT, the small box where the fibre enters your home. A steady power light and a healthy optical or PON light mean the fibre is up and the problem is downstream — your router or Wi-Fi. If the optical light is off or a LOS light shows red, no light is reaching you: that is a break or an ONT that has dropped its session, and it will not be fixed from inside the flat. Power the ONT and router off together for 30 seconds and let them re-sync.
Because Community Fibre often wires whole blocks and estates at once, a fault frequently affects several neighbours in the same building rather than just you. If your fibre is down, tether to a mobile network to stay online while an engineer is dispatched.
Why Community Fibre goes down: the usual causes
Running its own network gives Community Fibre one big advantage during outages: its faults are confined to its London footprint and do not ripple out from the shared Openreach network the way many other providers' do. The trade-off is that a young, fast-expanding build has its own failure modes. Most outages are local and physical — roadworks or third-party contractors cutting a duct, a damaged splice in a basement, or civil works in a borough where the network is still being extended. An ONT dropping its registration after a power cut is another common cause, as is scheduled maintenance, usually overnight. Because the line is symmetrical fibre, there is no copper to degrade in the rain and no cabinet to congest, so the sudden total drops you see are almost always a break or an equipment fault rather than a slow decline.
Is it Community Fibre or your own kit?
Measure to be sure. Run a speed test on your phone over 4G/5G with Wi-Fi off, then another from a computer wired into the router with an Ethernet cable. If mobile works but the wired test cannot connect, the fault is on your line or on Community Fibre's network; if other flats in your block are also dark, it is a building or area fault. Knocking on a neighbour's door is genuinely useful here, since Community Fibre often connects a whole building from the same point.
Keep slow apart from down. Community Fibre plans are symmetrical, so your upload should roughly match your download — if only Wi-Fi is slow while a wired test is full speed, the fix is your Wi-Fi, not the line. And check the units before you worry: a 1000 Mbps plan is only about 125 MB/s in a download manager, so a 100-plus MB/s download is exactly right.
How to reach Community Fibre and confirm the status
Community Fibre customer service is on 0800 083 0011, and the Community Fibre app shows any known fault at your address and lets you raise a report. To judge whether it is only you, line up two independent sources: reports by area on Downdetector and the network indicator on this page. During a larger incident, searching "Community Fibre down" on social media usually confirms within minutes whether your part of London is affected.
Frequently asked questions
How do I know if Community Fibre is down right now?
Read the status meter at the top of this page: it is built from public network signals over Community Fibre's address space and refreshes about every 10 minutes. Red suggests a genuine network fault on its London network; green while your own flat is offline usually means the ONT, the router or the cable in your building. Cross-check Downdetector and a quick 4G speed test before you call.
Does Community Fibre use the Openreach network?
No. Community Fibre has built its own full-fibre network across London rather than reselling Openreach lines. In practice that means its outages are independent of the Openreach faults that hit BT, Sky, TalkTalk and Plusnet, and they are confined to Community Fibre's own footprint — so a wider Openreach problem should not affect you, and vice versa.
My ONT's optical or LOS light is red — what does that mean?
The ONT is the box where the fibre enters your home. A red LOS light or a dark optical light means no light is arriving — a break in the fibre or an ONT that has lost its session, not something you can fix from inside. Power the ONT and router off for about 30 seconds; if the light stays red, report it, because it needs an engineer.
Community Fibre is only in London — does that affect outages?
Yes, in a helpful way. Because Community Fibre only operates in London, any outage is limited to its London network, and often to a single building, estate or borough where works are taking place. That is why checking whether neighbours in the same block are also affected is such a quick way to tell a local fault from a problem with your own equipment.
Community Fibre is slow rather than down — what should I do?
Community Fibre lines are symmetrical full fibre, so upload should roughly match download. Test wired and over Wi-Fi: if wired is full speed but Wi-Fi is slow, the fix is your Wi-Fi — reposition the router or add a mesh node. If even a wired test is far below your plan across several tries, log it. Remember 1000 Mbps is about 125 MB/s, so a 100-plus MB/s download is normal.
How long do Community Fibre outages last, and can I claim compensation?
A local fibre fault is often repaired within hours, though civil works to reach a damaged duct can take longer. If your plan is covered by Ofcom's automatic compensation scheme, you may be owed a set amount for each full day of total loss of service that is not fixed in time, so note when the outage began and any reference number.
