Hello, Toolserver needs a complete change of the officially assigned IP addresses. Every accessible service will be involved. This involves several maintenances that will cause interruptions. The maintenances will also cause interuptions for OSM. To see if everything comes up correctly reboots will be necessary on all regarding servers. I will start with parallel IP setup at the load balancers/head nodes damiana and turnera. I will do this next Thursday, 28th March 20-22 h UTC. The next maintenances will involve the login servers, web and mail servers. They will happen at Friday, 29th March 20 - 22h UTC and Sunday, 31th March 20 - 22h UTC. I hope everything will work after that. Cheers nosy/Marlen
