The Quiet app provides high-level technical details of how their app works:

This is actually very similar to one way I imagined a more server-less peer-based usage of ActivitiyPub working.

@badtuple I've debated making something that does that, but haven't ever pulled the trigger on it. I don't know of any other projects in this regard, but projects like NodeBB (and the threadiverse more generally) have done interesting work that could be adapted.
-
Hmm, has anyone made an #activitypub compatible server for play-by-post RPGs? That way people can follow along if they want, people could run their own server if they wished, but mainly as an alternative to discord which is where so many modern pbp games are hosted.

@FinchHaven Thanks for chiming in. I appreciate it.

@FinchHaven I am second guessing my choice of WordPress. I have been reading where people say one post or share from someone with a lot of followers will bring down your site each time... I am hoping, although some of the reading was recent, that devs have fixed it since then.
I am confident that the issues I am having is more towards my current, default WordPress configuration and not network related or even WordPress ActivityPub's fault.

Good luck with it
Those were just my first, easiest thoughts
Dropped out of network troubleshooting a good long while ago...

@FinchHaven Thanks. I changed the wording to the post. I just started troubleshooting the issue this morning and did a few things until I can break it down later overnight and troubleshoot more.
I added caching and going to add persistent object caching soon. I also notice php had low memory permissions so it was bottoming out quickly. I fixed that.
The WordPress instance sat idle until mid-February which explains why the jump is Latency.
I'm hosting on a VPS server through Namecheap at this time. Ubuntu 22.04, 12 GB ram, 8 CPU cores.

Also, to look at your instance on Fediverse Observer, your Latency more than doubled between January 2025 and February 2025, from 131.97 to 473-490 ms, and hit a peak of 757 ms on Jan 2026
Most recently: 538 ms @ Mar 2026

"Recently, when I post the new #HashTagGames post at 9PM est, it has taken 15 minutes or longer for all instances on the #Fediverse to get it ... why is because my #ActivityPub #WordPress enabled site is getting #DDoS due to the sheer number of instances trying to communicate with us when the game goes out."
I often check for details when I see posts like this, in the off-hand chance I might learn something
You seem to be on a single-user host via Namecheap
Assuming you're posting using TCP/IP, each packet you send out to the Fediverse requires an ACK packet in return before it continues, and most transactions involve scores of packets
Have you used something like Wireshark to look at exactly what you're sending out and receiving?
I doubt you're being DDoSsed so much as your very small instance is suddenly talking to tens of thousands of other instances, each one of which is trying to talk back to you all at once
Shorter: the Internet is not instantaneous
