The air conditioning suffered from the current heat wave in Strasbourg (temperatures reaching 40°C), and some servers have been disconnected, causing interruption of the following services : CDS portal, Xmatch service, A&A mirror, Aladin image preview.
All these services should be back on Monday, July 6.
Sorry for the inconvenience.
