Wow!
Grafana shows a huge increase of running CMS subtasks this afternoon:
https://monit-grafana.cern.ch/d/000000628/cms-job-monitoring?orgId=11&from=1580043214587&to=1580053294590&var-group_by=CMS_JobType&var-Tier=All&var-Site=T3_CH_Volunteer&var-Type=All&var-CMS_JobType=All&var-CMSPrimaryDataTier=All&var-binning=12m&var-measurement=condor_12m&var-retention_policy=sample

Running jobs:
15:48 CET: 344
16:00 CET: 436

92 new jobs within 12 min.
Given the fact that each new job makes >2000 internet requests and downloads >200 MB data this caused a total burst of additional >184000 requests / >18 GB data.
