The GTA VI pre-load, which opened on November 10, 2026, broke internet traffic records in the UK. Virgin Media O2 logged the highest peak and the largest daily data volume in its network’s history, while Openreach saw traffic rise 32.9% above a normal Tuesday. The game itself launches on November 19.

A pre-load lets players download a game before release day so they can start playing the moment it goes live. For internet providers, it means a very large number of consoles start pulling files of a couple of hundred gigabytes at roughly the same time. ISPreview puts the download at around 212 GB on PS5, varying slightly by console, while Virgin Media O2’s press release uses a figure of 190 GB.

The numbers from this event show how networks behave when demand arrives all at once. Online stores face the same pattern during big sales, public service portals face it when registration opens, and offices face it when they push a system update to hundreds of devices in one go.

Virgin Media O2 records on the first pre-load day

In a press release dated November 11, 2026, Virgin Media O2 said Tuesday, November 10, set two records on its fixed broadband network. Evening peak traffic beat the previous record by 3.8%. That earlier record was set during the Champions League semi-final between Arsenal and Atlético Madrid.

Total daily data volume beat the previous record by 4%. That record was only nine days old, set by the release of Fortnite Chapter 7 Mini Season on November 1, 2026. By 11:05 pm local time, the data downloaded that Tuesday had already exceeded the previous record for an entire day.

The surge started in the first minutes. Between midnight and 1 am, Virgin Media O2 broadband traffic was 51.6% higher than in the same hour a week earlier. By 9 am, total downloads were 73.3% above the equivalent period on Tuesday, November 3.

“GTA VI is already proving to be a record-breaking moment for our network,” said Jeanie York, Chief Technology Officer at Virgin Media O2, adding that the company had been preparing its network for demand at this scale. The operator also published a Strand Partners survey of 520 UK adults who expect to play GTA VI. Of those, 46% planned to download the game before release day.

Openreach data shows the hourly pattern

A fuller picture comes from Openreach, the access network operator used by many UK broadband providers. Openreach shared hourly traffic data for November 10, 2026 with ISPreview and compared it with an average Tuesday.

Over 24 hours, the Openreach network carried 377.98 petabytes, up 32.9% from 284.46 petabytes on a typical Tuesday. One petabyte equals one million gigabytes. The largest relative jump came overnight: at 4 am, traffic was up 94.9%, as downloads kept running at a time when everyday traffic is usually low.

Bar chart of Openreach network traffic growth during the GTA VI pre-load on November 10, 2026: up 51.6% at midnight, 94.9% at 4 am, 11.8% at noon and 24.3% at 8 pm compared with an average Tuesday

The largest volumes still came in the evening. At 8 pm, Openreach carried 28.43 petabytes in one hour, against 22.87 petabytes on a typical Tuesday. Game downloads were stacked on top of evening traffic that is already heavy with video streaming and other online activity.

That pattern matters for anyone planning capacity. The biggest percentage increase does not always land in the riskiest hour. The hardest hour is when a new surge meets a daily load that is already high.

How networks absorb downloads of this size

Large game downloads are rarely served straight from one publisher server. The files are distributed through a content delivery network (CDN), a set of servers that keep copies of popular files closer to users. ISPreview noted that CDNs should by now be helping to balance the load in the days after pre-loading began.

A CDN does not remove all of the strain, though. The data still has to cross each provider’s own network to reach homes, including the gateway equipment that connects subscribers to the core network. That is where one smaller UK provider, YouFibre, ran into trouble.

According to ISPreview’s report on the Virgin Media traffic surge, YouFibre told customers on November 10 about a network capacity issue caused by high demand for GTA VI downloads. One of its Broadband Network Gateways was affected, and customers around Yorkshire saw congestion. YouFibre resolved it with emergency traffic management to spread the load.

Comparison table of the GTA VI pre-load impact on three UK networks: Virgin Media O2 set peak and daily volume records, Openreach saw daily traffic rise 32.9%, and YouFibre had local congestion in Yorkshire that it fixed with traffic management

The wave may not be over. ISPreview sees a high possibility that release day on November 19 brings a day-one patch, plus extra load from players who did not pre-order. CNBC Indonesia also reported that providers in several countries have asked customers to expect slower connections for a few days.

For users in Indonesia, the UK records do not automatically mean slower home internet. Indonesian providers have not published official data on the impact of the GTA VI pre-load. Even so, international routes and CDN servers in Asia serve many countries at once, so network teams have good reason to keep an eye on surges like this one.

What this means for IT teams and online stores

The event is a clear, measured example of simultaneous peak demand. Online stores preparing for year-end shopping season, agencies opening online registration, and offices distributing system updates to many devices all face a similar pattern at a different scale. The following steps are worth considering.

Four steps to prepare systems for traffic spikes: map peak hours, put large files on a CDN, schedule downloads outside peak hours, and prepare a traffic management plan

First, map peak hours from your own data. The Openreach figures show that the heaviest load arrives when a surge meets normal daily peaks. Online stores should study hourly traffic from previous promotions and use those figures to size their servers.

Second, serve large files and static content through a CDN. Product images, videos, app packages and downloadable documents should not be pulled straight from the main server. Teams building a store or portal can design for this from the start through cloud computing services, so application servers only handle work that needs live data, such as carts and payments.

Third, let users download early and outside busy hours. Offices can borrow the pre-load idea: roll out operating system and application updates in stages overnight, and use local peer sharing features such as Delivery Optimization in Windows to reduce the load on the office internet connection.

Fourth, prepare a traffic management plan before you need it. The YouFibre case shows that one saturated network point can slow down an entire area. Organizations should decide in advance which functions get throttled first, such as heavy search or large reports, so that core transactions keep running. For retailers, this plan fits naturally alongside the inventory and point-of-sale systems covered on the retail management solutions page.

A similar lesson came out of the Google Cloud outage in London: systems that depend on a single path or location are more exposed when pressure builds.

Frequently asked questions

How big is the GTA VI download?

ISPreview reports that the GTA VI pre-load is around 212 GB on PS5, with small differences between consoles. Virgin Media O2’s press release cites 190 GB. Players should check the size in their console store and leave enough free storage.

Will the GTA VI pre-load slow down internet in Indonesia?

At the time of writing, Indonesian internet providers have not released official data on its impact. The documented records come from UK networks. If connections feel slow in the evening, the cause can vary and is best confirmed with the provider.

When does GTA VI launch?

Virgin Media O2 says GTA VI launches on November 19, 2026. Pre-loading opened on November 10, 2026, so players who pre-ordered can download the files before release day.

Closing thoughts

The GTA VI pre-load records show that even large networks work hard when a huge number of devices request data at the same hour. The operator that had prepared set new records, while one network point that was less ready was felt immediately by customers. If your organization is preparing an app or online store for a surge in users, the Merakit team can help design a cloud and CDN architecture that matches your traffic patterns.
