What this means
Cox Communications is reachable from all 4 probe methods.
If you still can't connect, the outage is on your side: DNS cache, VPN routing, ISP filtering, or a browser-level block. Try a different network or device to confirm.
What to try next
Try another network
Switch between Wi-Fi and mobile data, or disable your VPN. If it works there, the issue is on your primary network.
Up but slow?
Run the speed test, first-byte, TLS, and download timing with a published grade, plus a check of your own connection.
Browser reset
Try an incognito window or a different browser, a bad extension or cached error page can masquerade as downtime.
FAQ
Why is Cox Communications down right now?
Outages typically come from CDN/DNS issues, failed deploys, regional routing problems, or DDoS. We can't see Cox Communications's internal cause, we only confirm reachability from each probe method. If all 4 probe methods failed, it's a confirmed outage on Cox Communications's side. If only some failed, Cox Communications is up but blocking or mishandling a specific request type.
Is Cox Communications down for everyone or just me?
Look at the probe-method grid above. If every probe method succeeded, the issue is local to your network, flush DNS, switch networks, or disable your VPN. If two or more probe methods failed, the outage is on Cox Communications's side.
How often does isitdown.io re-check Cox Communications?
Every 5 minutes via background HTTP probes using 4 independent probe methods. You can also re-run on demand by reloading, the verdict above reflects the latest probe.

Methodology
- Probe
- We send a GET request to the target URL with each probe method and time the full response.
- Counts as DOWN
- Every probe method fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Counts as DEGRADED
- At least one probe method succeeds but at least one fails, the site is up but blocking or mishandling a specific request type.
- Detail
- Per-method results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
- Cadence
- Every 5 minutes, in parallel across 4 independent probe methods (HTTP/1.1 with strict TLS, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) from our edge network. We check probe diversity, not geography — if a site blocks a non-browser User-Agent or only speaks HTTP/1.1, the four cards show it.
- Rate-limited targets
- If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status, we do not flood the target to confirm the outage.
- Data source
- Our verdict is based on direct multi-method probes, every result above is a live network request, never a Twitter mention or DownDetector aggregate. User reports, when shown, appear separately below as a supplementary signal and are never used to determine the up/down verdict.
