On 20 February 2018, DigitalOcean indicated issues with block storage volumes on their NYC3 location. Block storage volumes are used by your server to host the blockchains of your node wallets.
They are currently investigating and working to resolve. However, as a result of the original issue, your server may need to be restarted.
To determine if you are affected, log into DigitalOcean and view the droplets panel. Look for the location of your droplet underneath its name.
If it is NYC3, log into your server's terminal and check the status of your wallet nodes with the command:
If any show 'STOPPED' or 'FATAL', your server may have been impacted. Your coins are safe, though you should go about restarting the droplet.
To recover, restart your server by running the following command within its terminal:
shutdown -r now
You'll be logged out of the droplet for a couple minutes as it reboots.
Once logged back in, give your wallets a couple more minutes to load. Your balances may not reflect accurately until the wallet and chain are finished loading. Check their status with the prior supervisorctl status command.
It's possible that some of your wallets will reindex as a result of the issue. This means they'll need to process their blockchains again which may take more than a few hours. (See: Checking wallet synchronization)
Unable to log in
If you're unable to log into your server's terminal, the droplet may have been switched off. To recover, within the DigitalOcean control panel, click the toggle shown below to Switch On.
Then, log in and verify the wallet status with the above supervisorctl status command.
