We need to restart extension1 (x1) primary database master, db1103, as part of T266483
There is no way to disable x1 on MW so we'll need to set it to read-only on MySQL and restart it.
x1 currently has:
- Databases: `flowdb`, `cognate_wiktionary` and `wikishared` database,
- Tables on the x1 wikis are:
```
+-------------------+
| Tables_in_enwiki |
+-------------------+
| aft_feedback |
| echo_email_batch |
| echo_event |
| echo_notification |
| echo_target_page |
+-------------------+
```
```
bounce_records
cx_corpora
cx_lists
cx_suggestions
cx_translations
cx_translators
echo_unread_wikis
reading_list
reading_list_entry
reading_list_project
urlshortcodes
wikimedia_editor_tasks_counts
wikimedia_editor_tasks_edit_streak
wikimedia_editor_tasks_keys
wikimedia_editor_tasks_targets_passed
```
The last time we did an x1 maintenance (T226358 and T250701) we used a bunch of tags, so I am tagging the same and subscribing the same people.
**Impact**: x1 will be on read-only for around 1 minute. Writes will not go through but reads will remain unaffected
**When**: Wednesday 17th Feb at 07:00 AM UTC
