Shared hosting environment migration with IP change and decreased downtime
A method, system and computer product for a migration of a shared hosting environment with an IP change is provided. Migration is performed with the help of a special tool—the migrator. For each migrated domain on the source server, the TTL (time to live) values are decreased on the source DNS server.

The migrator creates configuration of web sites and mail service on the target server and copies files and mail messages from the source to the target server; the migrator creates databases (if replication is not available) on the target server; and the migrator creates DNS zones with DNS records pointing to the target server. Once administrator checks that site works well on the target server, the migrator performs content sync and sets DNS zone on the source server as slave to DNS zone on the target server. |

Managing tunnel endpoints for facilitating creation of logical networks
Some embodiments provide a novel method for managing hardware forwarding elements (MHFEs) that facilitate the creation of multiple logical networks on a set of shared physical forwarding elements. The method uses a set of logical controllers that generate data that defines a set of logical networks, and a set physical controllers to distribute the generated data to the hardware forwarding elements. In some embodiments, each MHFE can serve as either a master MHFE or a slave MHFE for one set of computing end nodes (e.g., VMs, containers, etc.) in a logical network. To ensure proper routing of data packets to the computing end nodes, each MHFE sends to its physical controller an inventory (e.g., a table, a list, etc.) of the set of computing end nodes for which it serves as the master MHFE or the slave MHFE. Each physical controller forwards the inventory for each logical network to the logical controller for the logical network. Each logical controller maintains the master inventory of the MHFEs that are masters (and slaves if applicable) of the various compute end nodes of each logical network managed by the logical controller. After receiving a new inventory from a physical controller, the logical controller updates its records, resolves any conflicts while it is updating its records, and distributes one or more master/slave inventories for one or more logical networks that it manages to the physical controllers, which, in turn, pass this information to the MHFEs that they manage. |

Blockchain stochastic timer transaction synchronization
A blockchain may be used as a stochastic timer. The posting of a blockchain solution for verification may be a trigger that determines an event schedule. Because the only entity that knows when the solution will be posted is the solving entity, the solving entity may be rewarded with the ability to potentially exploit this knowledge. However, because the solving of a blockchain is a competitive process, there is a risk that if the solving entity retains the solution for greater exploitation, then another entity will post the solution and therefore gain the benefit. A blockchain stochastic timer can thus provide the necessary incentive for entities to invest computational resources into blockchain solutions. |

Wafer placement error detection based on measuring a current through an electrostatic chuck and solution for intervention
Methods and systems of detection of wafer placement error in a semiconductor processing chamber are disclosed. Methods and systems of interdiction are also disclosed to prevent hardware and wafer damage during semiconductor fabrication if and when a wafer placement error is detected. The method—is based on measuring a slope of current in an electrostatic chuck (ESC), which is correlated to lack of contact between the wafer and the ESC. Wafer placement detection at an early stage, when a heater and an ESC are being set up, gives the option of stopping the process before high power RF plasma is created. |
