The scheduled maintenance is the second step for a backend upgrade. We will move Diigo from current data center to Amazon cloud. You will experience a faster and more stable Diigo after the migration.
The planned maintenance window is Wednesday, Feb 11th at 0:00PM US PST. We expect the actual downtime to be approximately 1 hour.
Diigo 
Will this upgrade affect Chinese users? I am afraid the Amazon cloud is not available…
No. It won’t affect Chinese users. The IP we used in amazon is not blocked.
Does this mean that Diigo is going to be gone and we have to sign into Amazon Cloud for our libraries?
Does this mean that Diigo will no longer exist and we will need to sign into Amazon to access our libraries? Do we still sign into Diigo?
We hope that you let the user be able to backup/sync all his library with some external cloud service such as Dropbox/Google Drive/ if you are not going to release a stand-alone app that contains the library (like evernote) soon.
@Rox No. Diigo is still the same. We will just use Amazon EC2 servers to host your data. It’s faster.
@Tarek, there is a tool exporting everying in CSV format.
@Joel, not only faster but more reliable than in-house data center. Good job!
Is this Diigo a followup network ?
Is this blog a follow up one or no follow ?
When I use the function ‘share’ to send a link via an email It don’t work and I recieve ‘message not send’. This errors have began at Feb, 10, 2015 that have coincided with ‘move Diigo from current data center to Amazon cloud’. How do the function may be corrected?
Thanks!
