Working with Evernote Servers
One of the nicest things about Evernote is that it lets you save items individually on all supported devices and then access everything you’ve saved on any device. The only requirement is that all your devices be in sync, which usually occurs without your needing to do anything.
Get the inside scoop on Evernote’s synchronization mech-anisms, settings, and methods. Here’s how to better understand how Evernote works and to be confident of its capability to work for you.
The core of the Evernote service is a farm of servers that Evernote calls shards. Each shard handles all data and all traffic (web traffic and traffic generated by other apps connected to Evernote) for approximately 100,000 registered Evernote users. Because more than 80 million people use Evernote (at this writing), the math translates into around 800 shards.
Because each user’s data is completely localized to one (virtual) shard host, Evernote can run each shard as an independent island with virtually no crosstalk or dependencies. As a result, the issues on one shard don’t snowball to other shards.
Despite all the precautions and redundancies, problems are bound to happen occasionally because nothing is foolproof. Evernote understands these odds and has created a web page for you to check the status of its network: Evernote. If you’re having issues with syncing, you may want to check out this page to make sure that the problem isn’t something on Evernote’s end.
