What happens to digital signage when the internet goes down?

Quick answer: DigitalSignage.com screens keep playing when the internet goes down. The DigitalSignage.com SignPlayer downloads every scene, image and video assigned to the screen into its local cache and plays from there, so an outage does not blank the screen and scheduled changes such as menu dayparts still happen on the player's own clock. What stops is anything fetched live as it plays: web pages, YouTube, RSS and weather feeds, social walls and live streams. SignStudio shows the player as offline, and when the connection returns the player reconnects on its own, syncs any changes you published meanwhile and reports in again.

What keeps playing and what stops

Content	During an outage	Why
Images, video, PDFs, text and shapes in your scenes	Keep playing	Downloaded once and stored on the player
Scheduled campaigns and dayparts	Keep switching at the right times	The schedule runs against the player's own clock
Google Sheets, JSON and XML data zones	Show their last data, or go blank	Fetched as they play
Web Page component, YouTube, social feeds, weather, RSS	Go blank or freeze on the last state	Fetched live from the internet
Live streams	Stop	A stream needs a continuous connection
New content you publish during the outage	Arrives when the connection returns	The player cannot download it yet
Remote commands, screenshots, status	Unavailable until the player reconnects	SignStudio cannot reach the player

This is why a screen can show offline on the Screens dashboard while still playing normally on site. Offline means SignStudio cannot reach the player, not that the screen is dark.

How long cached content keeps playing

The documented answer is: until the schedule runs out. A brief outage of minutes is invisible. An outage of hours plays the cached campaign as scheduled. Over days, campaigns with end dates expire on the player's clock and the player falls back to whatever is still valid; if no valid campaign is left, the player keeps showing its last cached content. The practical limits are the end dates in your schedules and the storage on the device, which is why the failover guidance on this site is to keep at least 7 days of content on each player plus fallback content for longer outages.

Our documentation does not state a fixed number of days after which a player stops playing, so plan on the schedule, not on a timer. A site that has no internet at all should look at the on-premise mediaSERVER, a one-time $895 purchase that serves players over the local network, or at the Sneaker Net updater, which updates air-gapped players from a USB stick.

How the player reconnects

DigitalSignage.com SignPlayer is controlled from SignStudio over a real-time socket connection; behind a strict firewall it falls back to HTTP polling. Both are outbound only, over HTTPS on port 443 to the signage.me service, so nothing has to be opened inbound and no static IP is needed. When the network returns:

1. The player re-establishes its connection and reports online, with a fresh last seen time.
2. It checks for changes published while it was away and downloads them, then switches to the new content according to the schedule.
3. Remote screenshot, restart and the other commands work again.
4. If a command was sent during the outage and the player did not answer, send it again once the player shows online.

If the player does not come back when the rest of the site does, the troubleshooting FAQ lists the usual causes: an expired DHCP lease, Wi-Fi power saving, a captive portal on guest Wi-Fi, or a proxy that requires credentials.

Design for outages

1. Prefer uploaded media over streamed content on customer-facing screens. An MP4 you own plays from the cache; a YouTube link does not.
2. Give every live zone a cached fallback. Put a static image behind or beneath a web page, feed or data zone, so the zone is never empty when the connection drops.
3. Set a default campaign with no end date. Low priority, evergreen content assigned to every screen, so a screen is never left with nothing valid to play.
4. Extend end dates on long-running campaigns. A campaign that expires on Friday night during a weekend outage leaves the fallback in charge.
5. Size the player's storage for the content. Plan at least 16 GB on Android, a 64 GB SSD on Windows and a 32 GB A2 card or an SSD on a Raspberry Pi, and keep video encoded efficiently so the cache fits.
6. Use wired Ethernet where you can. Most overnight blank-screen reports trace back to Wi-Fi, not the internet connection itself.
7. Use a native player, not a browser tab. A plain browser tab has no reliable offline cache; when it reloads during an outage it has nothing to show. The native Windows, Mac, Android, Chrome OS and Raspberry Pi players cache locally and restart themselves.

What to check during an outage

Symptom	Likely cause	Action
Screen plays normally, dashboard says offline	Internet or firewall down, player fine	Wait, or fix the connection; nothing to do on the player
Videos play, web and feed zones are blank	Expected while offline	Fallback images cover this next time
Screen is black	Not an internet problem by itself; check power, display input and schedule	Follow the black screen guide
Player came back online but shows old content	The sync has not finished, or nothing new was published	Give a large playlist a few minutes, then Refresh Content
Only one screen is offline while the others are fine	That player's network link or power	Check its cable or Wi-Fi, then reboot it

Cellular and remote sites

A screen on 4G or 5G is sized by monthly data rather than speed. Heartbeats alone use 50 to 200 MB a month; a weekly image refresh adds under 1 GB; daily video refreshes can reach 5 to 25 GB. Content updates are bursts, and playback itself uses no data, so a cellular screen with mostly static content runs comfortably on a small plan and rides out carrier blips exactly as a wired screen rides out an ISP outage.

Frequently asked questions

Does digital signage keep working without internet?

Yes, for everything stored on the player. DigitalSignage.com SignPlayer caches scenes, images and video on the device and plays them through an outage, including scheduled dayparts, then syncs when the connection returns. Live zones such as web pages, YouTube, feeds and streams need a connection and go blank or freeze until it is back.

How long will a screen play after the internet drops?

Until its schedule runs out. Campaigns keep switching on the player's clock; those with end dates expire and the player falls back to whatever is still valid, or keeps showing its last cached content. Our documentation gives no fixed cutoff, so keep a default campaign with no end date and at least a week of content on each player.

Why does the dashboard say offline when the screen is still playing?

Offline means SignStudio cannot reach the player, usually because the internet, DNS, a firewall or a proxy is blocking the outbound HTTPS connection. The player keeps playing its cached content regardless. It reconnects by itself when the path is clear, and a screenshot then confirms what is on screen.

Will changes I publish during an outage reach the screen?

Yes, once the player reconnects. It checks for changes, downloads them and switches according to the schedule. A large video can take several minutes on a slow link, so allow time before sending Refresh Content.

What should I show in a web page or feed zone when offline?

A cached fallback image. Place a static image behind or beneath any web page, data, social or weather zone so it is never empty, and prefer uploaded MP4 files over YouTube links on screens customers watch all day.

Can digital signage run at a site with no internet at all?

Yes. The on-premise mediaSERVER, a one-time $895 purchase, serves players over the local network, and the Sneaker Net updater refreshes air-gapped players from a USB stick. Both are documented on this site; ask support which fits your site.
