In order to address a security issue, we are patching and rebooting many physical Labs hosts. The next round of this will begin at 15:00 UTC on Friday, which is 8:00AM San Francisco time. Interruptions will include: - A labs-wide network outage - Wikitech downtime - Horizon downtime - Possible failures in new instance creation None of the above should last more than a few minutes. For the most part Labs instances will be unaware of the outages, and no action is required from users. Apologies for any inconvenience caused! -Andrew
