[Development] IMPORTANT: Codereview scheduled maintenance break on Monday 7-Nov 7 am CET

I had a typo on the port number.
Of course the host key update affects the port 28418, where the Gerrit is running. Not 28419, like I stated earlier.
Sorry for the confusion.

Maintenance break is now over.

IMPORTANT: Server host keys have been updated.
When doing  a git command you might get warning like:

  @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

  @    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @

  @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

  IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

  Someone could be eavesdropping on you right now (man-in-the-middle attack)!

  It is also possible that a host key has just been changed.

  The fingerprint for the RSA key sent by the remote host is

  SHA256:EPuL0PAbNuXXoye7X93ARF7/XALxA5XNAaE3p6M/L3g.

  Please contact your system administrator.
This is expected. To fix this see the instructions in the bottom of this email chain.

Hi all,

There will be a maintenance break on the codereview.qt-project.org on Monday 7-Nov 7:00 am – 9:00 am CET.
Gerrit version will be upgraded to 3.5.3.

IMPORTANT:
Server host keys on port 29419 will be updated to support modern algorithms. Also the existing RSA key will be updated to a longer key size.
After the change the git commands may fail with errors about mismatched or changed host keys or host identification.
To fix this remove locally the old known host key (on Linux based remove the corresponding line in ~/.ssh/known_hosts -file)
and verify the new one (git will prompt for verification).

Here are the finger prints of the keys that will applied on 7-Nov:

ssh_host_ecdsa_384_key
384 SHA256:yMnqjnsJU0y6kfiyQQu8pYNGPFE7av5QxbeLdjTKNmk (ECDSA)

ssh_host_ecdsa_521_key
521 SHA256:kytLsqmLdG1KXLO/s3OxOajTYqf1+n7+YqqbOUzNbtE (ECDSA)

ssh_host_ecdsa_key
256 SHA256:El3+EYlXAGylCVo/Y/WYzPg7tS4fjejkepO1JVXUkb0 (ECDSA)

ssh_host_ed25519_key
256 SHA256:DwwqNluQyJVkOk+3bFMK6NwWYIGjMnqGP+R0k59e3CY (ED25519)

ssh_host_rsa_key
4096 SHA256:EPuL0PAbNuXXoye7X93ARF7/XALxA5XNAaE3p6M/L3g (RSA)
