At Xmarks, we are working to make the bookmarking service more resilient in the face of unforeseen disasters, such as this summer's widespread power outages and extreme weather events like Hurricane Sandy. To that end, we are upgrading the distributed database behind the Xmarks service, with a goal of achieving zero downtime failover between data centers and zero downtime maintenance. Unfortunately, we are not quite there and must incur some service downtime to make these changes.
The Xmarks bookmarking service will be unavailable on Tuesday, December 18 from 22:00 to 23:59 EST (Wednesday 03:00-05:00 UTC) as we perform the first phase of this process.
During this time, any attempts to update your bookmarks or retrieve them through the plugin or on http://my.xmarks.com/ will result in temporary errors; these may show up as error icons in the Xmarks plugins. Bookmarks already in your browser can be accessed as normal. At the close of the maintenance window, normal bookmark syncing can resume and Xmarks will resolve the temporary errors on the next sync.
If you have any questions or concerns, either leading up to or during the scheduled maintenance, please direct them to our support team by opening a ticket: https://buy.xmarks.com/supportticket.php
Thank you for your understanding and patience.
The Xmarks Team
