Yeah, Glitch blocked pinging services. Here is a section from their ToS
j. Infrastructure Integrity
We reserve the right to delete, suspend, or terminate your access to, or ability to use, any and all Services that we determine to be placing undue strain on our infrastructure. These changes were made in response to ping services on Glitch and our efforts to make the site more stable. You can read more about those efforts here.
That is not true. I ping my project to check how long it has been up to because I need to check the minutes, not hours. His/Her code is fine. It doesn’t really ping it. Glitch projects pinging themselves don’t keep them up, in fact, it is blocked. So there is nothing wrong.
Also, you don’t have to ping it, it is realitivally fast to wake ups. Mine is instant, but I have to refresh the cookie when it is offline for a long time
