1. A system to facilitate reconnection of stateful network connections after migration of a virtual machine instance, the system comprising:
a first host computing device and a second host computing device;
wherein the first host computing device is configured with computer-executable instructions to:
host the virtual machine instance prior to the migration;
identify a stateful network connection between the virtual machine instance and an external device external to the virtual machine instance;
independent of communications of the external device and virtual machine instance, transmit to the external device a first termination signal indicating termination of the stateful network connection, wherein the first termination signal is formatted to indicate that the first termination signal originates from the virtual machine instance; and
migrate the virtual machine instance to the second host computing device;
wherein the second host computing device is configured with computer-executable instructions to:
host the virtual machine instance subsequent to the migration;
identify the stateful network connection; and
independent of communications of the external device and virtual machine instance, transmit to the virtual machine instance a second termination signal indicating termination of the stateful network connection, wherein the second termination signal is formatted to indicate that second termination signal originates from the external device; and
wherein the virtual machine instance is configured, on receiving the second termination signal, to attempt to reestablish the stateful network connection.
