Mozilla VPN seems to be the culprit for vastly slowing down traffic.

I've been using Mozilla VPN for almost a year, mostly with little fanfare. Works just as advertised.

The past week my network has been slow. I've been running a whole host of diagnostics to my ISP but have not found a smoking gun. Today, I started doing a number of tests of the VPN itself.

I realize that a VPN will always reduce network bandwidth to some degree. THat has been the case since I have been using it. Today however (and I suspect for the last week) Mozilla VPN has just been a complete dog. Today from the same computer, using the same router, when the VPN is not installed and I am using the simple desktop version of speedtest available here https://www.speedtest.net/apps/windows , I get latency (ping) of 10ms, download speeds of 72 - 75 Mbps, and Upload speeds of 10 - 11 Mbps.

When I do connect the VPN I am getting latency (ping) of 25 - 30 ms, Download speeds of 30 - 35 Mbps, and Upload speeds of 5 - 6 Mbps.

Please note that I am choosing speedtest hosts to run against that are near the VPN endpoints geophraphically.

I have done these tests periodically in the past, and have typically seen the VPN affect my native throughput by 5 - 10%. Not by 50%.

I suspect this has been going on for about a week. I don't know where to check to see if Mozilla is posting and service problems, but this crosses the boundary from an acceptable degradation to a completely unacceptable degradation.

Any insights very welcome.

I just purchased Mozilla VPN a few days ago, and am seeing the same issue. I am paying AT&T for 300 Mbps, but normally only see about 100 Mbps--that is, until I started using Mozilla VPN--and suddenly I'm getting even slower speeds (via speedtest.net), and Internet drop offs. The past few days, I've seen pings of 94-114 ms, download speeds of 39-50 Mbps, and upload speeds up to 88 Mbps.

So, I'm wondering if a VPN is even worth the cost, when it has even been causing my Internet to drop off and completely disconnect, leaving me without service. I have spent a considerable amount of money for a wired, 'always on' connection (so I'm not sharing WiFi), but if a VPN is going to interfere, I have to weigh the pros and cons of that, too.

An AT&T technician just left my house. They came out to switch out my router and update my fiber optic wiring, in an effort to help me get the speeds I'm paying for. Apparently, when AT&T installed my fiber optic service four years ago, they installed unprotected fiber wires inside my walls (so they were replaced with protected wiring today). When the tech saw that I'm using a VPN, she said they can interfere with Internet and slow down broadband speeds.

I'm actually considering unsubscribing to the VPN, if it's going to destroy what little Internet speed I'm getting. Looking for help here, and as soon, as I don't want to lose my option of getting my year subscription money back.

I would appreciate anything you guys can tell me, to help me resolve this issue.

TIA, --Catherine
