Using a VPN didn't help my speeds. I was wondering if the VPN helping was just anecdotal but looks like it's helped more than one person. Maybe I can try a different VPN. Did you use the same VPN as
A VPN also should not help. A VPN is just another (or more) hops for the network traffic to go from the server to you, which should slow down things and not speed them up.
There may be some edge cases where the resulting route to the server may be worse with a "direct" connection compared to a VPN, but this should be very rarely the case.
Most likely the CDN is not picking the ideal server for you, I have seen this many times on different CDN providers, and also here on SLR. A year ago or so the CDN would often connect me with servers in the US (I am located in Europe) which of course leads to garbage latencies and bandwidth. For me it is working fine now for quite some time, but I can still see that others still might have problems.
And this is also a situations where VPNs might help, because the bigger of them have very large private connections between the continents so you do not rely on the slower public internet to cover large distances, and the VPN endpoint may be closer to the server then you.
But the VPN is just a bandaid in this situation, when the real problem is a wrong configuration of the CDN.
If you expect your ISP throttling your speed you should reach out for their support. Most western countries have more or less quite strict rules for network neutrality, which does not allow throttling of random services.
My speeds are inconsistent, sometimes very low, sometimes higher but not more than about half of what I get at other speedtest.
Which indicates a problem on the CDN site, and not throttling from your ISP. If your ISP throttles a certain service, there is no reason to assume it only does that at certain times. An overload of network traffic from your ISP might also be the reason, but in that case at the same time when SLR is slow everything else should be slow as well.
More likely the CDN is choosing a close/fast server when it runs fast, but a slow/far away server when it does not work well, for whatever reason.
