Last night around 9 PM, I was trying to upload a client project while a YouTube video buffered endlessly in the background. At first, I thought my router was acting up again — which honestly happens more often than PTCL users would like to admit. I restarted the modem twice, checked cables, and even switched devices before realizing the issue wasn’t from my side.
Turns out, PTCL has officially announced that users across Pakistan may experience internet disruption or slower speeds during evening hours between May 11 and May 18 due to maintenance work on an international submarine cable.
If you work remotely, play online games, stream Netflix, attend Zoom meetings, or even just scroll social media at night, there’s a good chance you may notice slower internet during this period.
What’s Actually Happening With PTCL Internet?
According to PTCL, an international cable consortium is carrying out repair work on one of the submarine internet cables connected to Pakistan.
Most people don’t realize how much Pakistan depends on undersea fibre optic cables for international internet traffic. When one cable develops a fault or goes under maintenance, internet traffic gets shifted to backup routes, which often become overloaded during peak evening hours.
That’s why speeds usually feel normal during the day but suddenly slow down after dinner time when everyone starts streaming videos, gaming, or downloading content.
I’ve personally noticed this pattern during previous cable issues too. Browsing websites still works, but heavier tasks like cloud backups, HD streaming, and large downloads become frustratingly slow.
Why Evening Hours Are Usually Affected First
Even if your package says “20 Mbps” or “Flash Fiber,” internet speed depends heavily on network congestion.
Between roughly 7 PM and midnight, internet usage spikes massively across Pakistan because people are:
- Watching YouTube or Netflix
- Using TikTok and Instagram Reels
- Gaming online
- Downloading updates
- Attending remote classes or meetings
When international bandwidth gets limited due to cable maintenance, those peak hours suffer first.
This doesn’t always mean the internet completely stops working. In most cases, users experience:
- Slower browsing
- High ping in games
- Video buffering
- Delayed uploads
- Random disconnections

What PTCL Users Can Do During This Period
Honestly, there’s no magic fix if the issue is happening at the backbone network level. But after dealing with similar outages over the years, I’ve learned a few practical tricks that genuinely help.
Download Important Files Earlier
If you have office work, software updates, or large downloads pending, try finishing them during daytime hours when traffic is lighter.
I usually schedule Windows updates and Google Drive backups before evening now because nighttime speeds become unpredictable during outages.
Use Lower Streaming Quality Temporarily
This sounds basic, but switching YouTube or Netflix from 1080p to 720p actually makes a noticeable difference during congestion.
Most people won’t even notice the visual drop on mobile devices.
Restarting The Router Won’t Always Help
One mistake many users make is repeatedly restarting the modem every five minutes.
If the slowdown is happening due to submarine cable maintenance, restarting your router probably won’t fix it.
I learned this the hard way after resetting my PTCL settings during a previous outage and making things worse for myself.
Keep Mobile Data As Backup
If you work online, it’s smart to keep a backup mobile data package active during these maintenance days.
Apps like:
- Zoom
- WhatsApp calls
- Google Meet
- Slack
often perform better temporarily on mobile networks if fixed broadband becomes unstable.
Pakistan’s Internet Infrastructure Still Faces Challenges
One thing this situation highlights again is how dependent Pakistan remains on international submarine cables.
Whenever there’s a fault, repair, or shutdown issue, users across the country immediately feel the impact.
Over the years, we’ve seen:
- Slow browsing nationwide
- Social media outages
- Gaming lag spikes
- International routing problems
And for freelancers or remote workers, even a few hours of unstable internet can become stressful.
I know several people who now keep both PTCL and mobile hotspot backups specifically because of situations like this.
Common Mistakes Users Should Avoid
Don’t Factory Reset Your Router Immediately
Unless your internet is completely dead for hours, avoid resetting everything during temporary slowdowns.
Avoid Fake “Speed Boost” Apps
During outages, random apps claiming to “boost internet speed” start trending online. Most of them do nothing useful.
Check Official PTCL Updates First
Before assuming your connection is permanently damaged, check PTCL’s official social pages or support channels for maintenance notices.
What To Expect Until May 18
Based on previous submarine cable repair periods, most users will probably experience occasional slowdowns rather than total outages.
Some areas may barely notice it, while heavy internet users during evening peak hours could feel the impact more strongly.
If your work depends heavily on stable internet, planning ahead for the next few evenings is honestly the smartest move.
