Now CFD Online is finally up and running on the real production server again. Holding my thumbs that the problem will not return.

[CFD Online Team @cfdonline]

Site has been down for a period. Something broke during live cloning of the virtual server. Managed to get the site up and running on a backup server. I do not think any data has been lost.

[CFD Online Team @cfdonline]

Still having problems with the site.

@KuralamuthanV The virtual server is always available at https://t.co/AC3J5KyNqZ. But this virtual server can be run on different physical servers. I got it up and running again on a backup server, but it broke once I started to live-clone it back to the production server. Not sure why.

[CFD Online Team @cfdonline]

The server is now up and running. Had to restore a backup and some data from Friday lost, see https://t.co/H749ipQR3k

We are having problems to restart the virtual servers running CFD Online after an OS update. We are working on it ...

[CFD Online Team @cfdonline]

An OS update on the servers broke the forum database. The database has now been repaired and the forums should be up and running again.

[CFD Online Team @cfdonline]

Had some memory issues on our servers that brought the SQL server down. Do not know what caused it, but a reboot solved it. Lets hope it does not come back.

[CFD Online Team @cfdonline]

Updating OS on servers. Site might go down for short periods during reboots.

[CFD Online Team @cfdonline]

Site is up and again. Please report any problems here. Not sure what happened. With some manual interventions I was able to boot the virtual server, and once up it boots normally again. Not really sure what the problem was 🙃 Virtual servers are fantastic... while they work 😅

[CFD Online Team @cfdonline]

After a few hours of sleep I finally manually was able to start the virtual KVM-server running CFD Online. It requires manual boot though, not sure why, so something is broken. Expect sudden down-times today while I debug this.

[CFD Online Team @cfdonline]

CFD Online is down after an OS upgrade. We are working on it, but currently have no estimate on the down-time, it will take hours, perhaps days. No data has been lost, but the virtual server running the site refuses to start after the OS update 🙁

[CFD Online Team @cfdonline]

Something is seriously wrong with the virtual server. Expect a longer down-time. 🙁

[CFD Online Team @cfdonline]

Updating the OS on our servers and having some problems to get the site up right now...

[CFD Online Team @cfdonline]

@erayyceylann I do not know, everything is running on a virtual KVM machine and this virtual machine refuses to start after the OS update.... could take seconds or days to fix, sorry.

Updating hosting system on our servers today. Site will go down for short periods.

[CFD Online Team @cfdonline]

New SSL certificate received and installed. Now you should not get any warnings when you visit CFD Online.

[CFD Online Team @cfdonline]

We forgot to renew our SSL certificate so you will get a warning when you visit CFD Online now. Still safe to visit though and a new certificate has been ordered and will be installed asap.
