Known Issue - Maintenance Window Required

We have completed a key step in the resolution of the issue described here.

We are working to resolve a known issue of Coveralls suddenly sending multiple PR comments to customer PRs, rather than one, updated PR comment that replaces older PR comments. This issue has been active for ~2.5 weeks.

Our solution involves the need to change a column type in a production database table to accommodate larger integer values.

With hundreds of millions of records and constant read/write activity, we will need to make this table change during a maintenance window scheduled for this weekend, Sat Jun 29-Sun, Jun 30.

We will attempt to perform our changes on Saturday evening US PDT, but will update this post when the exact window is known.

We will keep this "incident" open until the associated maintenance window has closed.
