Is there a problem with the Garmin Connect backend?

Having same issue with vivofit
Still not working as of 2.39pm 26/08/2014.

Same here at 11:19 pm mountain time. Synced vivofit and steps are there but the activity or heart rate is not there. Looks like another activity lost to never never land.

I am having the same issue too. I have tried both my watches (FR610, FR70), both my ANT+ usb sticks, I even uninstalled and reinstalled the Garmin express and deleted all the data on my computer. No luck. All Garmin Express says it that there was an error transferring my data. It does not specify what the error is, but I also see a strange entry for weight from like 1998 or something (I have no idea what that is) that says Done next to it when my current activities Error. I tried to enter the activities manually on Connect.garmin.com, but I kept getting errors there too that said my start value was invalid. Nothing I tried to enter manually would save, and the error messages there were also very unhelpful.
I am very frustrated. :mad: This started with me last Friday and I was intermittenly able to transfer data, but nothing is going today.

HO is in my time zone and it's been down since at least 3:00 pm. They don't know about this unless Delhi tells them?

Same problem vivofit. Started today 8/25/14

Same with a FR610. I tried to refresh the internet browser, clean it, restart the computer, restart the watch but no success. Last night it worked this morning it didn't. GC says the sync was done but the last activity is not there, so the connection with the Ant+ apparently is fine.
As Endomondo has no straight way to transfer the data from the watch info such as course, elevation and the HR frequency through the activity are lost when the entry is done manually.

I too struggled for about an hour trying to figure out what the problem is. Acitivities from both my 310XT not uploading.. Didnt know that several users are facing this problem. I infact did a hard reset of my watch to lose my work out data. Crazy !!

Similar problem with GC and my Edge 500. Worked fine yesterday.
Hangs uploading today. Usually upload takes 1-5 minutes. 1 hr is not enough today.
Will leave current attempt active for next 6-7 hours and then retry to see if this was a Garmin website problem.
FWIW, many software changes are done on weekend to minimize user impact. This is my first attempted upload after the weekend.
Bad software or hardware change on Garmin end in last 30 hrs???

same problem here - seems that Garmin had this problem last month and have closed that thread because the bug was fixed, but took them ages to respond to their customers - typical bad service from garmin

Having the same issue. Garmin 710. I get an error on upload using Garmin Express. Switched to the classic version of Garmin connect, and it just hangs. Then saved the .fit file to my desktop and tried a manual upload, and it just hangs and wont upload, the last time it did this in Western Australia it was a time setting problem so I tried changing that but no luck

Uploaded to another well known/popular cycling workout/segment tracking website without a problem....
