[English version below] Liebe Mitarbeiter, im Zuge von Wartungsarbeiten am HRZ koennte es sein, dass das INS Netzwerk am Mittwoch von 10h bis 13h nicht erreichbar ist (siehe weitergeleitete Mail). Das heisst insbesondere, dass eventuell remote Einloggen waehrenddessen nicht moeglich sein wird. Beste Gruesse Die Systemadministration --------------------------- Dear colleagues Due to maintenance at the HRZ, the INS network may not be reachable between 10AM and 1PM (see forwarded message).

Im Zuge dessen wird der Raum zwischen *10 und 13 Uhr* zeitweise stromlos geschaltet. Davon sind folgende Dienste betroffen: * Im *Datennetzbereich Poppelsdorf *(Liste s.u.) kommt es während des o.g. Zeitraums zeitweise zu einem kompletten Datennetzausfall. In anderen Bereichen der Universität kann es aufgrund von Redundanzumschaltungen der Datennetzkomponenten zu sehr kurzen Verbindungsunterbrechungen (wenige Sekunden) kommen. * *Backup (ISP)* steht ab Montagmorgen (30.06.) bis zum Ende der Wartungsarbeiten nicht zur Verfügung. * Die Leistung des *zentralen Mailsystems* wird während des o.g. Zeitraums zeitweise reduziert. Dadurch kann es zu einer erheblich ver ringerten Performance und zeitweisen Störungen kommen * Bei allen *weiteren Serverdiensten des HRZ* (u.a. BASIS, CMS, eCampus sowie die Institutsdienste, die UniVM nutzen) erwarten wir keine Unterbrechungen. Allerdings kann es ab Dienstagabend (29.06.) bis zum Ende der Wartungsarbeiten zu geringfügigen Performanceeinbußen kommen.     ---------- Folgende Gebäude sind von dem Datennetzausfall ("Datennetzbereich Poppelsdorf") direkt betroffen: * Carl-Troll-Strasse 6 * Carl-Troll-Strasse 6a * Carl-Troll-Strasse 10 * Carl-Troll-Strasse 31 * Endenicher Allee 19a (Friedrich-Hirzebruch-Allee 6-8) * Endenicher Allee 19b (Friedrich-Hirzebruch-Allee 7) * Endenicher Allee 19c (Friedrich-Hirzebruch-Allee 5) * Karlrobert-Kreiten-Strasse 13 * Katzenburgweg 3 * Katzenburgweg 4 * Katzenburgweg 5 * Katzenburgweg 7/9 * Katzenburgweg 9a * Katzenburgweg 11 * Katzenburgweg 13 * Meckenheimer Allee 166a * Nußallee 9 * Nußallee 11 * Nußallee 13 * Nußallee 15 * Nußallee 15a (Friedrich-Hirzebruch-Allee 4) * Nußallee 17 Folgende HRZ-Dienste sind hiervon betroffen: /Backup, BONNET, E-Mail/ -- Mit freundlichen Grüßen Hochschulrechenzentrum / Zentraler IT-Service Universität Bonn Wegelerstr. 6 53115 Bonn Tel.-Nr.: 0228 / 73 2751 Mail: betrieb@uni-bonn.de Link zu dieser Meldung: https://www.hrz.uni-bonn.de/de/betriebsmeldungen/1623856840998 <https://www.hrz.uni-bonn.de/de/betriebsmeldungen/1623856840998>
