This mail contains some very important information that affects a fair number of people and services on HECnet. So please read through it, and if you need to take action, please do this in a timely manner. I'm here to help with whatever, but I can only work on things from my end of things. Background: Update is a computer club at Uppsala University. As such, it has enjoyed a lot of support from the University over a long time. However, recent development have now led us to a point where the University is no longer willing to support Update. The main way the support have been provided is through a computer room where machines have been running, electricity, and network connectivity. All of this is now going away. Basically, and the end of this year, Update will have to have moved out of their current location. This means that any machine Update currently have running will need to move. Update have found a location of their own that they now started to rent, and most things will be moving in a few weeks from now. There are also unfortunately a need to reduce the size of Update's collection of hardware since the size of the collection is just too big for Update to afford to keep. You might hear more on that separately, but I'm not going to go into that any further than saying that Magica and other large iron is currently safe, and will be moved. But it's going to be difficult to run these machines for the time being. Primary effects: Mim.Update.UU.SE, Psilo.Update.UU.SE and any other resources used by HECnet will go offline. I'm not sure about the exact date, but expect this to happen in a couple of weeks from now. This means any Multinet links to MIM will go down, and will not come back up. Any bridge connections to Psilo will also go away. Also, the HECnet mailing list will stop working. Update is working on getting services back up and running in their new location, but exactly in which form we are able to is unclear, and it is also unclear what network capacity there will be, or when anything will be back. Changes happening on HECnet: Because of the things mentioned above, there is a plan in place to keep HECnet up and running. Thanks to Peter Lothberg, a lot of functions and services currently at Update will move to Stupi. MIM:: (Mim.Update.UU.SE) has already moved to Stupi, and is now known as Mim.Stupi.NET. Still the same nodename on HECnet. The old Mim (Mim.Update.UU.SE) is still up for the time being, as XMIM:: Any Multinet links to Mim.Update.UU.SE are going to have to move. There will be two alternatives: . HECnet-1-1023.Stupi.NET is a PyDECnet router which I intend to be a major hub for HECnet. Located in Stockholm with good network capacity. . Mim.Stupi.NET, which is just the same machine, and can accept the same links. Any bridge connection to Psilo.Update.UU.SE are going to have to move. There is one alternative: . HECnet-1-1023.Stupi.NET. Same router that takes Multinet links. As mentioned above, I aim for this to be a major hub going forward. XMIM:: will be around for a few weeks, but will go down in the not distant future. All current Multinet bridges to it will have to migrate in order to keep working. Else those links will soon stop. MIM:: will continue service HECnet with the nodename database, just like before. It also will continue to act as a mail gateway for anyone using that feature. Mail from inside HECnet to the Internet will continue to be handled as MIM::<user at internet.host> Mail from Internet to HECnet will need to be addressed as <node>::<user>@Mim.Stupi.Net Web services at Mim will continue as well, but obviously at Mim.Stupi.NET. Same with ftp, rpm, and all other things. In order to reduce the number of issues that might pop up, I am going to try and get Mim.Update.UU.SE setup as a CNAME to Mim.Stupi.NET, so that most things will continue to work even using the old hostname, but there might be hiccups here. Be aware. The mailing list I'm still looking into how to handle. I'll get back on that soon. Next steps: I want that people have have links to Update to contact me, and we can move the links over to new endpoints. Keep in mind that I might take a day or two to respond to each individual. But I'll try to move fast as I don't know when things will stop operating in the current setup. Also, any issues, problems, funny stuff, or whatever, please reach out to me. I'm also going to keep an eye open for routing becoming odd in the face of things here, and will poke people when I see things that just look wrong. Of course, I have no insight into any Cisco equipment, so there I will just have to hope and trust that each person running such gear have things set up in a reasonable way. Well, that's about all I can think of right now. Now you all know what is happening, and anyone having links to Update will need to take action. Anyone using other services from machines at Update might also see problems as this all happens. And once more, many thanks to Peter Lothberg, who have been very helpful in finding a solution to this problem. (And yes, I wish Uppsala University had done things differently, but that is not anything I am in any position to affect, or make much comments on.)
