The method of some embodiments takes a corrective action to automatically recover from a split-brain failure occurred at a pair of high availability (HA) edge nodes of the network. The HA edge nodes include an active machine and a standby machine. The active edge node actively passes through the network traffic (e.g., north-south traffic for a logical network), while the standby edge node is synchronized and ready to transition to the active state, should a failure occur. Both HA nodes share the same configuration settings and only one is active until a path, link, or system failure occurs. The active edge node also provides stateful services (e.g., stateful firewall, load balancing, etc.) to the data compute nodes of the network. |

System for preparing a device for offline or low-bandwidth use
Techniques for preparing a user device for use in a location having limited network access include replacing data in the device cache prior to the user device reaching the location. A length of time until cached data expires, a length of time used to replace the cached data, and a length of time for the user device to reach the location are determined. Portions of the cached data that will expire while the user device is within the location are replaced. The time at which the data is replaced is based on the length of time used to replace the data and the length of time for the user device to reach the location. While the user device is in the location, functions that transmit large quantities of data may instead be replaced with more efficient data types or queued for later execution after the user device exits the location. |
