The #Guppe situation happened because all groups were on one server, so when that server went down all the groups did too.FediGroups is a good immediate solution for getting groups up and running again, but it's also a single server so it's vulnerable.As a long term solution we need to have groups hosted on many different servers. If one server goes down, groups on other servers could carry on.Techy people might be interested in hosting/forking Guppe from source at https://github.com/immers-space/guppe

p.s. For those wondering how this can happen, the .pe domain which gup.pe used has a highly unusual clause which allows anyone to buy the domain 12 days *before* it expires:"The .CH, .ES, .FR, .LI, .PE, .SG, .COM.SG, .COM.AU, .ORG.AU, .NET.AU TLDs must be renewed 12 days prior to the actual expiration date. If not renewed, the domain will enter the redemption stage right away regardless of the number of days left until expiration."https://www.namecheap.com/support/knowledgebase/article.aspx/9916/2207/tlds-grace-periods(Thanks @anonax for info!)
