For about 2 days, the forum has been loading and working very slowly here. I am not sure whether something is going on with my Internet connection, or the problem is with the forum itself. I have tried restarting the modem and the router, using different Web browsers, etc., but there is no difference. The forum used to load very quickly, but now it seems to take 5+ seconds to process every request.
I have done a few speed tests to check the Internet connection, but they come out normally. Other websites also seem to load as usual.
Has anyone else experienced any slowdowns, or am I the only one?
It feels as usual for me, and I practically live here. Not always ultra snappy but I think that’s just a huge ruby on rails app being a huge ruby on rails app… Certainly no 5s+ wait times.
It used to be snappy, but suddenly became sluggish yesterday, and has stayed this way since then. Especially the very first load may take even 15 seconds or so. After that, it is usable, but still something feels off.
This will probably reveal nothing of much use, but you can do a speedtest to DigitalOceans servers and check if you’re getting acceptable bandwidth and/or latency.
I think this forum (currently) runs in DigitalOcean’s AMS2 data center (at least that’s what a traceroute from my side suggests) and they have a speedtest there:
(For me only the manual test via HTTP test file download worked - compare the speeds you’re getting with the speeds you would expect from a “usual” speedtest. I was getting speeds well exceeding 200 Mbit/s, so the thing seems to be working)
If you’re getting horrible speeds, it’s probably some overloaded transit provider.
The speeds are not great. It is impossible to know what they had been before the slowdown though.
On the other hand, this is the maximum bandwidth of my home Internet connection.
However, the situation seems to have improved a little today. Still not as fast as it used to be, but the forum is loading quicker and responds to requests snappier than yesterday.
Well, I do live on the other side of the globe than Amsterdam, so I am not expecting super fast speeds or anything like that, but this is still way slower than it used to be. The previous rates were from the morning, now in the daytime it is even worse.
I am curious what the problem is though, as both my provider’s speed test and other popular speed tests like https://speedtest.net or https://fast.com do not have any issues. Below is a result of doing a speed test with a server located in Amsterdam (not DigitalOcean though), and everything seems normal here.
This is how it looks like. Also, when pinging forum.syncthing.net, there is no packet loss, so the connection is stable, just very slow.

@tomasz86 I don’t know if this applies to you, but I sometimes have to reboot my AVM FritzBox and I don’t know if its the hardware bug of 7490 or my provider but after a re-dialup to DSL it works much faster again then noticable by speed tests.

Yeah that really sounds like a transit provider/connection that is choking.
Diagnosing that is a fun thing (not really), you can try and compare traceroutes to providers in a similar region and see what routes give you slow speeds and what routes have good speeds. At some point there should be one transit provider that only appears on the slow routes - that’s the bad player.
Oh and when doing traceroutes, always remember that routing in the www is a mostly asymmetrical thing, e.g upstream route does not equal downstream route. Testing the downstream route requires a traceroute from the other side, which isn’t a trivial thing to do unless you have network access.
You can also try and talk to your local ISP, if you’re lucky they can do something. But I wouldn’t bet on it.
Yes, I highly doubt that they would do anything, as long as their own speed test shows no anomalies. If everything was working slowly, then it would be a different story, but right now this seems to be limited to specific servers/regions. The other websites that I use on a daily basis mostly seem to work as usual.
I have tried rebooting both the modem and the router, and also inspected the configuration, but there has been no change. When it comes to the hardware, everything seems to be working fine.
I just wanted to say that the forum seems to be loading quickly again. I do not now what the problem was (and nothing has changed on my side in between), but it seems to be gone now.
Just for the record, below are the current speed test and tracert.
