iCloud Calendar locked/not available/not synching w/iPhone 6s

I went to the Apple Store Genius Bar today for this issue. They had a major server thing that messed up lots of folks. Looks like it is fixed on their end, perhaps it's just taking a while to fix our end?

Glad I'm not alone. Happening on multiple devices. Updated to El Capitan on my iMac and the problem persists. It's erratic. And, sometimes different error messages are being generated. But the one you've posted appeared verbatim for me a number of times today. I'm in touch with a Senior Apple Tech on this (I also have another strange calendar related issue which I thought could be related to this) so we'll see if the engineers find anything.

Just to throw in my two cents, I've been experiencing the above errors on both my desktop, laptop, plus getting weird syncing issues on my devices as well and not just with iCal but also with my Reminders too.

I spoke with Apple Support by phone and they said the same thing - they were having lots of server related issues today but it's been resolved on their end.

I guess now we wait till it trickles down to our ends.

Just when you thought it was safe....

Happening again. Errors all day yesterday like others, then worked last night. Just opened Calendar on my MBP (with all latest updated for 10.10.5 except I have not let it do Safari 9.0), and getting the errors again. This time was one of the messages that has a "Try Again" button, but got the error "...try again later" this time.

So, it's not fixed. BTW, using the following link to status if Apple systems, showed all green with no messages that there was any issues or problems. In fact it stated: "There are no reported issues at this time." Seems that they need to work on status updates as well. And its still all green with that same message: "There are no reported issues at this time."

I would call Apple Support to let them know what you're experiencing so that perhaps they can log it.

Of course. And, as of 11a MDT this morning, it's still happening.

I'm also having this issue. Unfortunately, this morning I don't have 3 spare hours to spend on the phone with Apple Support.

When I tried them by phone yesterday I got through in less than a minute but that was probably because I tried them around 1730-1800 MST.

Funny you guys have mentioned that the issues have returned because initially it didn't for me; however I've noticed within the last 15 minutes, my iCal is back on the fritz again as yesterday. I'm guessing Apple hasn't fully ironed out their issues with iCloud and this new update yet.

Exactly same situation as described above on September 30 and now on October 1st. Reminders and Calendars not syncing. Same error message. Occasionally Notes go offline as well. Started yesterday around 10 am and persisting at 2:25 today.

Yup, I concur....lots of things on the fritz!

This is happening to me as well. It is super annoying, especially when it seems they say it is corrected on their end yet it has not changed anything on the end of the user.

I hope they get this figured out. Thankfully you posted something to let me know I was not alone. I did everything they said to solve the issue and still didn't help anything. It all started when I upgraded to El Capitan.

Same here....El Capitan broke it! lol

This problem started for me yesterday or the day before. I am on Yosemite on my laptop and still on iOS 8.4.1. So, while the cause of the problem may be an upgrade, it is affecting older OSs, too.

The error message has change for me, though. Now it says "Your calendar couldn't be refreshed. The connection with server p01-caldav.icloud.com has been closed. Try again later."
