Our main wxWidgets site server (also hosting the docs and wiki) will begin a 1 hour maintenance window on Monday, July 12, 2010 at 16:00 UTC.
During this window, the server's access layer switch will be rebooted, resulting in about 5 minutes of network downtime. Since this is being performed now though, I will be taking advantage of the same window to also take care of a (not desperately needed, but helpful) hardware upgrade I've been delaying for a while now waiting for an appropriate time. That will result in up to 10 to 15 additional minutes of downtime.
Sorry for any inconvenience and also the somewhat late notice.
Regards,
Bryan Petty
