We keep an updated list of services that are paused or that are experiencing other problems at our status page. You can visit there for a comprehensive list of issues related to services as well as IFTTT downtimes or other incidents.
Currently, we've been having longer term issues with the services listed below, please visit the status page to get the latest details. You can also subscribe for updates there so that you will get an automated alert to know when they are working again without problems.
Skype - 1:1 chat with the IFTTT bot isn't working, but if you create a new conversation with only the IFTTT bot, it should function in the same way. Hopefully this workaround is useful to know about!
Sina Weibo - We have reached out to Sina Weibo to make a plan to address the problem, as action is required on their side to solve the issue. Unfortunately, we do not have an ETA for when this will be resolved. We will update this page as details become available.
Edyn - We reached out to Edyn about this problem, as action is required on their side before the service can be operational again. There is unfortunately no ETA for when this service will be un-paused.
