[ALUG] Mint mirrors

Anyone else having issues refreshing the mirrors? (WiFi is fine generally so I don't think it's problem at my end.) This isn't a one-off. I get this message: <<Failed to fetch http://www.mirrorservice.org/sites/packages.linuxmint.com/packages/dists/tes... 503 Service Unavailable [IP: 91.230.243.15 80]Some index files failed to download. They have been ignored, or old ones used instead.>> Bev
