Visit fourm is unstable recent days?

From China.

I consider it’s should be a forum issue rather than my own, because i can visit other sites at same time.

I hope this is a good news, our user traffic on the forum has increased significantly?

I am browsing from Japan. I have not had any problems connecting to Crystal Forum recently.

Flagfox (Firefox extension) speculates that the server is located in Canada, but of course I do not know if this is correct.

Anyway, here’s an interesting map of submarine cables around the world, and although Crystal users are scattered all over the globe, they can communicate with each other thanks to the infrastructure.

I wanted to write “they can communicate with each other”, but I noticed that LLM had translated it as the exact opposite, “they can’t communicate with each other”, so I have to fix it. Did AI want to say something? :upside_down_face:

In fact, we surpased the limit of 100k views/month and I’m always in fear that at some point Discourse will shut us down until we start paying the next tier :sweat_smile:

Scrap that, I looked again and there was a mistake in Discourse. Now it shows a bit more than 30k pageviews per month. I guess the marker for “you are surpassing your tier” was wrong (and it’s now fixed).

The internet is a network of networks, and faults can happen anywhere and lead to all kinds of partial disruptions. Being able to reach a set of sites does not mean you can tell whether you would be able to reach any other site.
It’s entirely plausible that there could be some connectivity issues somewhere along the path between you and the forum server.

I’m not aware of any issues in general forum availability apart from what’s listed on https://status.discourse.org/

Please see following screenshot.

This issue happen on yesterday and the day before yesterday, connection was created, but very slow, finally result in timeout, will investigate for more details if happen again.

Unfortunately, I don’t think anyone can help you with this.

You’ll need to do some digging on your end to try to figure out what’s causing these connectivity drops. Could be related to your network configuration (DNS, proxy, VPN etc.), or outside of your control (e.g. network peering). Tracing the route to forum.crystal-lang.org could help to pinpoint where the connection fails.

This issue happen again

I start found this issue at 2024-11-08 04:20 UTC, forum start to work at 2024-11-08 04:25 UTC,

mtr output loss 94.4%

Following is the traceroute output compare for the first time (failed) and second time(success), but ignore all same part.

I don’t know how to trace this issue, the only reason I can guess is that the server was overload, causing a downtime, because at the same time, i can visit all others often visited site.

Hi,

I think that Discourse is hosting not just the Crystal community forum but other communities as well on the same instances, which could lead to outages due to traffic or DDoS attacks.

I also noticed that https://status.discourse.org/ doesn’t show probes for APAC, South America, or Africa.
The HTTP headers suggest there’s no CDN like Cloudflare, and the site is served directly by Nginx.
The IP is from a Canadian hosting provider, Hurricane Electric LLC, so the issue could be with the hosting provider.

My trace for compare:
