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

This is not resolved. I have just updated to ios 9, lost all calendar events and icloud.com says 'Due to account maintenance, Settings is currently unavailable'. The issue is real.

Have you tried logging out of iCloud and logging back in?

I'm successfully connected now. And sync is working, the event that hadn't synced that got me noticing the issue is there now.

I've had the same all day with Yosemite. Upgraded to El Capitan still the same. Apple support tried to help on the phone using screen share but couldn't fix it. Told me it was an Apple server issue that it will soon be resolved their end, if not by 7.45pm tonight I was told to call back. These things happen, still not good, driving me a little nuts. Wasted a lot of time thinking it was my end. Reminders not syncing either.

I continue to have the same icloud calendar issues too. I've tried recreating my calendar events from Outlook 2011 to iCal, tried creating new calendars in 'On My Mac' instead if iCloud, getting ready to cable my phone and laptop to try a sync - spent many hours on this for days now. I'm wondering if I am making things worse and should just leave everything alone and wait until it is fixed, or as one person mentioned, switch to Google calendar.

Yes, I've tried this and everything else under the sun, exhaustively. I work in IT as a software developer so it's not my first trip to the rodeo. Still having issues, and still missing all calendar events, still locked out of icloud.com calendar. Just updated to El Capitan on macbook yesterday, same issues...

All fixed. Apple tech support did it. Spent 3 days trying myself but as one poster said it just wasted time and got me frustrated. Great Apple support guys from Ireland. Even they were locked out from my stuff but in the end they worked it out.

How did they solve it??? I am having the exact same problem since a couple of days ago!

I am having the exact same problem as of 10/25/15. Anyone else having this issue currently???

Error:

The server at p01-caldav.icloud.com is currently unable to handle the connection for account “iCloud” due to a temporary overloading or maintenance of the server. If this continues you should contact the server administrator.

Can't access Calendar through iCloud.com either.

Please help. I use a Macbook Air and iPhone 6Plus.

I am experiencing this problem now too. It started as another person said when I tried to restore a back up from the night before (accidental calendar entry delete). The apple customer service folks could not have any better people or communication skills. They know just what to say when I am trying to polite but clearly am frustrated. They truly are consistently great. The issue I am now having with Apple is their response time when people use their products for small businesses. This is now the 2nd calendar issue I've had the past month. After the 9.0 phone upgrade my iPhone touchscreen did not work for a month. I spent a lot of time trying to get it fixed, only to find out it was two upgrades in that fixed it finally. Now I am locked out of my iCal. It is now taking too much time Apple to get to these issues when people rely on these systems for work.

Sorry to interrupt

My calendar is not taking updates from iPhone 6. My iPad is syncing fine with iPhone. Any ideas please?
