[Incident] System outage and Mercurial instability - Tuesday 8 November

Some of you will be aware that os.mbed.com, the Online Compiler and Keil Studio were all unavailable for a period of time yesterday. After the services were recovered at around 6pm GMT you may have still seen errors relating to Mercurial repositories and have been unable to complete Mercurial actions. This problem persisted until this morning but should now be resolved.

The underlying issue should now be resolved and we apologise for the interruption to services. If you continue to see any issues please report them here.

UPDATE: We are unfortunately continuing to have issues with performance and stability. While most services should be running as normal Mercurial actions remain unavailable.

UPDATE (1515 GMT): os.mbed.com, the Online Compiler, Mbed Studio and Keil Studio Cloud are running as normal with the following exceptions:

  • mbed.com code pages for Mercurial repositories are currently unavailable. This includes many popular examples and a large proportion of Mbed 2 libraries. GitHub-hosted code pages continue to work as normal, including the official Mbed OS examples.
  • Library management for Mbed projects in Online Compiler, Mbed Studio and Keil Studio Cloud will only work with GitHub-hosted library repositories. Mbed-hosted Mercurial library repositories will fail to load or update.
  • Creation of new programs from templates in Online Compiler is not working (you will see a Repository server error occurred message).

The team continues to work on a solution to these remaining issues. We will update you once normal service resumes.

Is there any update on this issue?


Hi @Jsvens. Status remains the same as above. We expect to deploy a fix today but I will keep you updated on this thread. Thanks for your patience.


UPDATE (1700 GMT) - Code pages on os.mbed.com are available again and mercurial actions are working as expected.

Thank you for your patience while we worked on this issue. Please let us know here if you continue to see problems.
