On 14 May 2019, an Intel security vulnerability was disclosed which affects its processors, and notably that of cloud providers such as DigtialOcean, upon whose servers your admin is run.
DigitalOcean is rolling out mitigations to this across their platform which they've indicated should not affect server uptime.
Additionally, you can take steps to ensure your server is more secure by updating to the latest Linux kernel. This is done by running a couple commands to update and power off your droplet, then switching it back on.
⚠️ Note: While your droplet is powered off, your machines will temporarily go to the 'Sorry, we're down' screen, until you switch the droplet back on.
Updating to the latest kernel
In your server's terminal, copy and paste the following single command:
apt update && DEBIAN_FRONTEND=noninteractive apt install -y linux-virtual
Within a minute, you should see the message 'done' and a new command prompt.
Rebooting your droplet
In your server's terminal, run the following two commands individually:
supervisorctl stop all
After the second command, your connection to the server will be closed and the droplet powered down.
In your DigitalOcean control panel, click on your droplet details, and toggle the 'Off / On' switch in the upper-right corner.
Logging back in
If all went well, you should be able to log into your server after a minute. You can then view the status of your lamassu-server, admin, and blockchains with the command:
This should show them as 'RUNNING', after which your server and machines should be operating as normal.
