As a registered Android developer, today I, along with thousands of other devs, got the following email from the Android Market Support team. The email informed me that the developer console, which is the interface used for publishing new apps, will be unavailable this Thursday, November 18th from 10 a.m. to 4 p.m. PST. The customer-facing Market itself will continue working just fine (or so I hope at least), but no new applications or app updates will be allowed.
Now, what could this update be for? It could be as simple as the promised Market housekeeping that was announced 5 days ago, although it seemed far less serious, and I got the impression that it did not require any downtime.
