My VPN Was Fast All Day—Then 10 P.M. Made It Unusable

At 10:07 p.m., the architectural model stopped rotating on my screen. The client could still hear me, but the browser-based review room had frozen on the lobby entrance while I was describing the roof. I turned off my camera, lowered the model quality and refreshed the page. It loaded again, moved for twenty seconds and stalled. The same VPN had been fast that afternoon, so I blamed the 5G router and restarted it while six people waited in the meeting.

I was working from an apartment in Riyadh, presenting a late revision to a design team in London. The client’s review environment used a regional access rule, so the VPN was not optional. I needed it to enter the workspace and load the full 3D model.

During the afternoon, that setup had been uneventful. The model opened in under a minute, the camera moved smoothly through each room and file comments appeared almost instantly.

At night, the same connection behaved like a different service.

The router came back online. I reconnected the VPN, reopened the meeting and reached the same frozen lobby entrance.

This time, instead of restarting everything again, I looked at the clock.

The slowdown had begun at almost exactly the same hour on the previous two evenings.

I had been testing the VPN at the wrong time

My daytime speed test showed more than 300 Mbps. At 10:15 p.m., the connection still produced a respectable headline number, but the model hesitated whenever I entered a detailed room. Camera movements arrived late. Textures blurred, sharpened and blurred again.

The timing matched Saudi Arabia’s broader internet-use pattern. The country’s Communications, Space and Technology Commission identifies 9 p.m. to 11 p.m. as the daily peak for internet activity. (Gov) Opensignal has also found that consistent quality on Saudi fixed-wireless networks falls during the evening as more households share the available mobile capacity. (Opensignal)

The slowdown was not random. It was rush hour.

That explained why restarting the router had achieved so little. The device had reconnected successfully, but it had returned to the same crowded network.

A brief public account from another user described the same clockwork pattern: normal daytime latency followed by sharply worse performance each evening. (Reddit) The useful detail was the repetition.

Until then, I had been testing the VPN when the network was quiet and assuming those results represented the whole day.

The client meeting exposed what happened when everyone else came online.

The established provider kept winning the speed test

The VPN I had started with was a large, familiar service. It had years of public history, a polished application and enough locations to make troubleshooting appear straightforward.

I selected the nearest available server.

The model loaded quickly, and for a moment I thought the restart had worked. Then one of the clients asked me to open the lighting layer. The browser hesitated, the cursor stopped moving and the meeting app warned that my connection was unstable.

I switched servers.

The next location showed a slightly lower ping. The model remained usable for two minutes before the textures blurred and the viewport froze again.

A third server produced the fastest speed-test result of the evening. It also produced the shortest stable presentation.

That was when the numbers stopped being helpful.

The connection could move a large amount of data during a short test. The model needed something different: hundreds of camera movements, texture requests and interface updates arriving steadily while I spoke.

An impressive burst could not compensate for repeated pauses.

I could not observe the mobile operator’s or VPN provider’s internal traffic-management rules. I could see the result: each server started well, then became erratic as the session continued.

The provider’s broad network was a genuine strength during the day. At night, it gave me more locations to test without solving the presentation.

Ethernet removed Wi-Fi from the list of suspects

Before blaming the wider network, I needed to rule out the apartment.

I connected the laptop directly to the 5G router with an Ethernet cable. I paused every background download and removed the tablet, television and game console from the local network.

The apartment was quiet. The architectural model was the only demanding task left.

The VPN still slowed.

That result moved the bottleneck beyond my desk. Changing the Wi-Fi channel or sitting closer to the router would not repair congestion farther along the route.

I briefly joined the meeting without the VPN. The call became smoother, but the client’s review environment rejected the connection because of its regional access rule.

That test proved the laptop and meeting app were capable of working. It also brought me back to the original problem: I still needed a VPN.

The question was no longer how to make the apartment Wi-Fi faster. It was which VPN could remain useful when the evening network became crowded.

Reducing the model solved the wrong problem

The client agreed to reconvene thirty minutes later, giving me time for one more workaround.

I exported a lighter version of the model. I removed high-resolution textures, reduced reflections and disabled several lighting effects.

The smaller project loaded through the established provider and moved more smoothly.

It was also no longer the project the client needed to approve.

The stone finish looked flat. The glass no longer reflected the neighboring tower. Most importantly, the evening-lighting layer that had caused the original design question was missing.

Technically, I had made the session easier to transmit. Practically, I had removed the evidence required for the decision.

That failure clarified the standard.

I did not need a connection that worked after the task had been stripped down to fit it. The full model was the task.

The smaller app handled the busy hour differently

Before the second meeting began, I opened OnlydogVPN and selected the preset intended for a weak or unstable connection.

The app did not send me into another round of country comparisons. I started the connection, reopened the full model and waited.

The loading bar reached 100 percent.

I rotated the camera through the lobby. The textures remained sharp. I opened the lighting layer that had frozen the first meeting and moved from daylight to the evening scene.

Nothing stopped.

When the clients rejoined, I began at the same entrance where the earlier presentation had failed. We crossed the atrium, compared the stone finishes and moved onto the roof. One participant asked me to switch repeatedly between two material options—a sequence that had previously brought the page to a halt.

Both versions loaded.

Twenty minutes later, the team approved the revision.

The connection had not produced a spectacular new benchmark. It had simply stayed useful during the busiest part of the evening.

The smaller app uses an HTTP/3-based transport that recovers quickly when the network becomes uneven. Instead of allowing one delayed piece of traffic to hold up the rest of the session, it keeps independent parts of the connection moving. (IETF)

On the screen, the effect was easier to understand: the evening network stumbled, but the presentation did not.

The hotspot became a backup instead of the plan

Near the end of the review, the 5G router briefly lost its connection.

Earlier, that interruption would have ended the session. I would have disconnected the VPN, enabled my phone’s hotspot, selected another server and reopened the model while the clients waited.

This time, I switched the laptop to the hotspot and returned to the review room.

The picture softened for a moment. Then the model continued from the same roof view.

I did not restart the VPN or reload the project.

That smaller result mattered because nighttime congestion is rarely one smooth slowdown. The connection can move from acceptable to unstable and back again as local demand changes. Recovering from those shifts was more useful than giving me another server to test.

After the approval, I moved the laptop back to the home router and uploaded the final screenshots. They finished while I answered the client’s last two messages.

The evening had finally become boring.

That was exactly what I wanted.

Daytime speed had hidden the real comparison

The next morning, I repeated the tests.

The established provider was fast again. Its nearby locations produced excellent numbers, and the full model moved without difficulty. Had I tested only at 10 a.m., I would have concluded that nothing was wrong.

At 10 p.m., the difference returned.

The larger service performed well when the network was quiet. The smaller app remained usable when the network filled up.

It has fewer locations, a shorter public history and fewer independent reviews than the established provider. Those limitations matter when someone needs a specific country endpoint or places the greatest weight on years of outside scrutiny.

They did not decide whether the client could review the building.

I had started with the usual comparison: choose the nearest server, run a speed test and trust the highest result. Nighttime congestion showed why that method was incomplete.

When a VPN becomes slow only at night, daytime speed tells you what it can do on an empty road. The result that matters is whether it still carries your work when everyone else comes home.
