I work for a school board and many of our teachers/students are no longer able to access websites that have their DNS routed through CF on a consistent basis. This has been going on for a week now. It’s not limited to one site, but numerous sites. Essentially, a teacher will be instructing the students to use an interactive site (managed by CF) when all of a sudden, students start seeing ERR_CONNECTION_TIMED_OUT. It seems to occur when 10+ users are interacting with the site at the same time, as though CF feels like it’s under attack. I’m a teacher and am not responsible for the network, but wonder what might be causing these timeouts. They typically start on one PC then within a minute, no PC can interact with the site, and then 10-15min later, all PCs can view these sites again.
I suspect they are being rate limited by the site owner.
It’s not cloudflare under attack. Site owners use cloudflare to determine allow or disallow the traffic or does not reach their site by using a set of “tools” that cloudflare offers. Mikita, Black & Decker, Hilti, Milwaukee, et al don’t tell people how they can and cannot use tools they create. Nor does Cloudflare.
If you have a rayid and timestamp, you can share those with the site owner and they can determine why the students receive the error. I suspect the the traffic is from one IP and the sudden bursts are blocked. Error number, rayid, etc will all help. You can also ask the site owner to create a rule to allow your IP, if they are willing to do so.
What’s really strange is that it’s been working fine for years and all of a sudden it’s an issue. The site owner tells me there’s absolutely no change on the CF side.
Can you ask them if they see the block in their dash? That is the first step to allowing it.
It may not be them, it may be your IP. IP reputation may be a good thing to investigate. Are you connecting here using the same connection the students are using? (I do not see any issue with the IP you are using here)
