Moodle in English: Cloudflare

Cloudflare

Hi,

I'm enrolled on the MOOC Moodle course 2015 and use an iMac for navegating with IOS Yosemite.

Up until about an hour ago I could enter the LearnMoodle.net and participate in the course etc

Now I cannot enter the course and every time I attempt to log in I get a message from Cloudflare Error 525 saying that the SSL handshake had failed. Try again later.

Now I don't know who these people are and have not (intentionally) installed anything from them, nor signed up with them etc.

I've restarted the iMac, the router, and still the same.

I can enter any other web site except LearnMoodle.net. I also tried to send Mary Cooch, the Course Moderator an email, but Cloudflare kicked in again.

Is there a problem? Is the site still up? Who are Cloudflare and how can they interfere with me trying to connect to the moodle course

thanks

PS - writing this on my wife's laptop

Moodle uses Cloudflare for a whole range of reasons, spam, speed - it is not something you have on your computer.

The site is up and OK for me.

Thanks Derek,

I can enter now, but it was scary for a while thinking that someone was trying to interfere with things,

All the best,

James

Hi Folks,

There have been issues recorded both on internal and external monitoring tools with the server hosting learn.moodle.net over the past few days which I have been monitoring.

The issue has actually been traced to an attack directed at a non-Moodle server in the same rack at our datacentre.

I've been in communication with our datacentre provider, whom have mitigated/null routed the malicious traffic, and as such, should have resolved these issues.

In this case, the root cause of the 525 and 522 errors were actually a communications issue between CloudFlare and our hosted servers caused by these attacks.

We apologise for the inconvenience caused by these attacks.

Happy Learning!

Hi Matt,

I appreciate time taken to help me out

Here's hoping that whoever tried to interfere with Moodle's learning platform may flounder around in empty seas,

On with the learning...

Hi Matt,

Thanks for your reply. I was also working on an iMac and initially thought the problem was my end. It's such a shame when people think it's a good thing to just attack and destroy stuff

Cheers
