I have an Arduino which has been successfully sending data to Pachube, then Cosm, now Xively for years. I have a page to monitor the data (www.iphealth.info) which displays png images using this code for about 8 different data feeds: img src="https://api.xively.com/v2/feeds/63142/datastreams/2896DB79300EC.png?width=800&height=212&c=F53527&duration=1day&title=Hot%20Tub&b=true&g=true&scale=auto&timezone=-8"
This has been working successfully for literally years until yesterday which I am getting a "Xively Server Error" image instead of my data image for all of the data feeds. I have checked the Xively site and my data is still being successfully loaded into the site. However, I can't get any data out of the site. I have changed nothing. I can see the GET requests and all it says is error 503. Has Xively changed something?
