Delicious API Outage

Why you can’t currently sync your Delicious account using Yummy.

Update 10 April: It appears that the Delicious API is available again and you should be able to sync your bookmarks in Yummy again.

For what it’s worth, I don’t feel that Delicious communicated the problems very well — their blog said, incorrectly, that the API was working — and the amount of time they’ve taken is clearly disappointing. Sadly short of hosting our own bookmarking service, there is little that we Wandle Software can do when this happens.

At the time of writing most users will not be able to log into or sync with their Delicious account using Yummy or any other third party clients. The cause of this is Delicious moving data centres:

We are currently in the process of moving our data center. The entire maintenance window is expected to be from Friday April 3rd at 8:00 p.m. PT until Saturday April 4th 9:00 a.m. PT. During this time you may experience interruptions when saving and retrieving links. We are anticipating a full site outage at some point during that window,  but we are expecting it to last less than 1 hour.

It appears that they hit, or nearly reached, this target for their website but there are a number of unresolved issues around the periphery (feeds, importing/exporting links). They have not explicitly mentioned the API — the method by which Yummy accesses your bookmarks — but it’s certainly not working for me and I have received a number of support requests.

It appears that some work is ongoing. Over the weekend I was getting “503” errors (“Service Unavailable”) but as of Tuesday morning requests are failing with “invalid certificate” errors. If you’d like to validate this yourself, you can do so with the following command (replacing username and password with your actual username and password):

curl ‘’

I can only apologise for this outage and wish that there was something that I could do to help. In the meantime, I am waiting to submit Yummy 3.0.2 in case there are some required changes that they have not currently documented.
